Xià Fěi and Vein’s Dual Powers
Vein and Xià Fěi hold the powers of Foresight and Hindsight –
here's how I came to believe it.
Get ready for a lengthy post—this is the first in a series. (30 mins read).
Have you heard of the dual power theory?
Let me explain this beautiful theory first caught by @miyamiwu
(GIFs and correlating posts can be found here and here).
For those who missed it, Vein and Xià Fěi’s frames in the LULL Bridon arc credits feature VFX that spill into each other’s frames. As seen in her post, this does not happen with any of the other four characters, all of whom have confirmed powers.
We know that Link Click never does anything without a reason! What does this mean, and why are these two characters highlighted over the others?
Well Miyamiwu threw it out there that maybe it correlates to them having a dual power. And that theory makes so much sense.
Where have we seen the use of dual powers? We've seen dual powers used before with Lu Guang and Chéng Xiǎoshí, as well as with the siblings Li Tianchen and Li Tianxi. So, this isn’t something new. In fact, of the 7 confirmed characters with powers, 4 of them are in pairs. This makes it highly probable that two new complimenting characters who act as a duo are also connected in this way.
The symbolism is clear: the two share something deeper, just like the other powerful pairs. If four others can have dual powers, why not Xià Fěi and Vein, a pair so tightly connected both in contrasting personalities but equal and parallel in their relationship?
Now that I've explained this dual theory my goal was to figure out and prove which powers makes the most sense for either of the two to have.
To help me I've set up two cannon-bound rules that helped me find what it is.
Rule #1
Dual powers means the characters would either have parallel powers with complementary abilities or opposite powers that act as a counterbalance to each other.
Vein and Xià Fěi are constantly contrasting in these frames. Not only do the characters themselves contrast personality-wise, but their friendly dynamic complements each other. Given this dynamic, their powers would either need to complement or contrast with one another, or exist in the fine line between. It also goes to show that assuming Vein has smoke or immortal/resurrection powers would not work, because it needs a fitting connecting power.
Rule #2
There’s no reason to assume Link Click's powers are elemental. Based on what we've seen, Powers are tied to photography, time travel, or something related to the body or the mind. Introducing elemental powers would, in my opinion, mess with the established lore.
Assuming Xià Fěi has light powers doesn’t quite fit, even if it aligns with Rule 1 about having a parallel or opposite. Similarly, the theory of Xià Fěi having fire powers falls short if Vein’s doesn't seem like he would complement or contrast with that power in any way.
In my quest to narrow down the possible powers, I couldn’t help but find a loophole that had me wondering why Xià Fěi and Vein's eyes always glow so brightly, as if their power is constantly active. Even the other main characters' eyes dim when their powers aren't in use. This led me to a third rule—more hypothesis than canon-based, so your free to ignore it—
My biased Rule #3 - If both character’s power is one that stays on, it could be a passive or constant ability, always active but perhaps unnoticed until the right moment.
This rule genuinely backs you into a corner, but it only managed to put my last two remaining theories on a pedestal...
So, after digging myself into dozens of holes including loopholes to find potential powers that actually fit within a time-travel story, I finally hit on foresight and hindsight—and suddenly, everything clicked. Maybe its called link click because everything always clicks into place. hahaha....just pretend I'm funny.
These concepts not only make sense for both characters story arcs, but they’re backed by existing theories and new evidence I've uncovered. Now, I’ll dive into each of their respective powers, explaining the why, how, and what that support my theory.
Vein:
"Immediate Foresight"
Memory that does not transcend time, but transcends a series of moments.
Vein’s foresight works differently from Lu Guang’s—while Lu Guang’s power transcends time, Vein’s memory doesn’t carry over through each reset. I will stand by my belief that Vein didn’t know or recognize either Lu Guang or CXS before they were introduced to each other in episode 3— otherwise he would have simply killed them both.
While it looks like Lu Guang is on the edge of having both foresight and hindsight, I'd like to argue his power is more akin to clairvoyance. The difference in these powers is significant, but different enough for it makes sense for characters to have such similar abilities. Let me explain further.
Vein's power is PREDICTIVE
Lu Guangs power is TRUTH
Foresight - Vein's power is about predicting what might happen, based on the present circumstances. It’s more about a sense of anticipation or intuition—He would know what’s likely to happen. The where and how is clear, while the why and when remains predictive until within that moment.
Clairvoyance - Lu Guang’s power is about seeing specific details of the future, present, or past. He wouldn’t just predict what might happen; he has seen and experienced clearly both the past and future as if it were happening right in front of him. It’s about truth—the direct and clear perception of events, like he’s watching a film.
Since the director mentioned that Lu Guang always stays within his own timeline, I don't believe their powers see different timelines or possible outcomes, but rather 'the timeline's current outcome' in varying levels of clarity.
This view of Foresight aligns with Vein's almost superhuman reflexes,

I invite you to take a look at this scene until you REALLY understand it. On second glance there's something subtly off about the timing of Vein's reactions.
Study how swiftly Vein moves—it looks effortless. Too easy. Upon closer inspection, it even feels like Vein's own movements anticipate a frame or two before than the other even prepares to strike. Like he is one full moment ahead of each strike.
I have several frames here for example (this gif is originally 69 frames long)
While many anime characters can dodge like this, few do it with their eyes closed for three full swings without some kind of 'extra sense perception.' So I'm calling it evidence. Here Vein is showing complete confidence in his knowledge that he won't get hurt.
Just the fact that he stands still with that smug ass little smile screams that he is in control of the situation.
I'm hypothesizing that Vein learns the truth of the moment only within that moment; everything before is predictive. The closer he is, the clearer the information becomes. In that instant, he can dodge every strike because their next move shifts from a probability to a complete certainty. This gives him a sense of control and explains why he often looks so pleased.
I believe Vein is constantly downloading new information about his opponent and surroundings mid-battle, making him the perfect, constantly adapting adversary.
Vein is the embodiment of 'right place, right time,' and I doubt need to elaborate further. But I'll show some more GIFs instead.
This post is kinda long already but I also invite you to look into the Vein vs. Shao Yuanyuan fight as well. Because it feels like another use of his foresight abilities (Video link here)
and finally Vein's fatal limitation.
If too much is happening in too short a time, it’s possible to slip through the cracks of his foresight. He may fail to react to an immediate danger simply because his attention is divided between too many things. While he might have the right information, he is still human. In a scenario like this, Vein could potentially be open for attack but never taken completely by surprise.
So why was Vein blindsided by his own death?
There could be better theories to this part specifically, but maybe Vein never saw the possibility of the attack coming, because Vein's death was never supposed to have happened. It was too fast, and everything he thought would happen changed too quickly. Simply because a more powerful third party had inserted themself into the situation. (From what I understand Lu Guang changed something in their timeline and Vein had never been killed before).

The REAL genuine fear shown when Vein is called by his real name, and during the heart attack show how caught off guard he was. His mind racing, dare I say it had little to do with the fact that he couldn't breathe, but that there was a flaw within his foresight. That he was finally unable to take control of his precious moment. He didn't know what was going on until it was too late to prevent it.
But there is nothing wrong with Vein's foresight, because he still figures it out. But at the moment of his realization, Vein's death is already in motion—an attack happening in real time without even touching him, its not something that he can run away from.
And it is this eye opening realization on the brink of death where Vein is given the answers he's looking for.
He knows his killer, he knows what happened... and all he can do is laugh at having been one-upped. It's all so very interesting—and he would love to see who plays the next piece in this game of chess.
Vein's death is now a certainty. His own tricks used against him.
And his final words,
“So that’s how it is…”
I'd like to slide in another extra piece of proof for my Foresight theory.
This is the 6th episode's cover art. I think its pretty self explanatory.

Thank you so much for bearing with me, but we're only halfway done!
I already cut this bad boy into two separate separate posts too!
Next up....
Xià Fěi:
"Hindsight"
The tragedy of only ever figuring it out in hindsight.
Power born from memories and a grief that transcends the present...
"I’ve made up my mind.
No matter how bizarre the truth,
I’ll find out what happened."
The idea of hindsight comes from it being the inverse of foresight, and fitting Xià Fěi's potential character development.
I propose that he always had the power and it wasn’t 're-awakened' until Vein’s death. With Vein’s foresight gone, Xià Fěi's hindsight is born.
I think Xià Fěi always had the ability but was too young or traumatized to use it. His time at Chéng Wěimín's school raises questions. There’s a solid theory that the school was full of children with powers. (here and here).
(if you look up this scene you'll see Chéng is mouthing something, and from there we never see young Xià Fěi's eyes again, as they remain cast in shadow).
There are a lot of inconsistencies with this new information, wasn't Felix only an exchange student for college? What's with this scene?
What did "it's time," mean?
Here me out, what if Xià Fěi's memory was altered by Chéng Wěimín?
Xià Fěi seems unaware of what 'Bahati' was. He doesn't seem to know about the fire or the meaning of the word. If he remembered he could've helped them- or maybe warned them. But instead he was perfectly comfortable helping CXS question his previous boss, as well as Vein. Also how interesting is it, that he ended up working once in the same place that he went to school in at one point??
Xià Fěi feels like a character that follows the theme of returning back to the past. If not during the Bridon arc, that at least because we known off screen he's going to dedicate his life to finding out what happened to Vein.
Another thing that stood out to me during episode 3 was when (time stamp 14:30) when CXS said "Bahati" there was a magical sound effect. I study these Link click sound effects a lot and they're always happening. Mostly when someone notices something or when one could make the case that someone is subtly using their power. For example the sound effect shows up the most around Vein and Lu Guang. And its always the same sound effect. What if Xià Fěi remembers when the name is spoken, but anything related to CXS's father is a trigger word for a memory wipe on the subject?
Another piece of Xià Fěi's story. (Found by @joyokosuka, post here)
I want to believe Vein's interest in Xià Fěi has to do with their close connection and not just because there was a subliminal connection that comes with dual powers. If you believe in fate and all, which I’ll get into the next post. But I don't think either were actually aware of Xià Fěi's power, as it wouldn't have re-manifested until Vein's death.
It also makes sense, because Xià Fěi was open to powers existing.
Xià Fěi discovering his own past, and using his gift of hindsight would open up a whole can of worms for everyone.
The good and the bad, and the past that should've stayed buried.
I imagine Xià Fěi will be pretty upset when learning about the past and revisiting his memories before Vein’s death. It’s going to destroy him if he figures out that Lu Guang and CXS were involved.
I could see him using his power in a way that might allow him to re-experience or analyze past events but not actually go back in time. He will constantly search and long for for what he missed out on.
And if not to attempt revenge… then for closure.
Xià Fěi is taking up the gauntlet of an unwanted legacy for closure. How sad and ironic that Vein could've potentially been using his power along side him but Xià Fěi never realizes until the death of his counterpart.
Xià Fěi's power gives an ulterior meaning to what he told our mains.
“but I’ll remember the time I spent with you guys forever”
It's so haunting. Knowing he was backstabbed by his friends. This feels like a self-fulfilling prophecy.
The tragedy of hindsight.
Now after explaining where Hindsight would fit into the plot, I'll share the rest of the evidence for why Xià Fěi's power is Hindsight, more than just because he is Vein's inverse/parallel.
In another post by @miyamiwu (Click here) beautiful theory by the way.
There was one thing she said that stood out to me.
She explained that “In Mandarin Chinese, time is viewed in a vertical fashion. The past is above you, while the future is below you.”
Because of this I asked my friend for an impromptu lesson in Mandarin, to help me analyze that the name 夏斐 (Xià Fěi) can be linked to the idea of time.
Thank you so much to Yuqianqian 🌸💕 for dealing with my madness.
In Mandarin the past and future is viewed in a vertical fashion only through a spoken fashion.
Let me introduce you to “The Four Mandarin Chinese Tones” which are used to identify the TONE (shēngdiào) of a word. You use each tone to help you pitch your syllables. All Chinese words have tones.
First tone: a level and higher pitch
Second tone: rising, start from a lower pitch and end at a slightly higher pitch
Third tone: falling rising, start at a neutral tone then dip to a lower pitch before ending at a higher pitch
Fourth tone: falling, start the syllable at a slightly higher than neutral pitch then go quickly and strongly downwards
The reason the future is viewed downwards And past is viewed upwards is because they pitch upwards and downwards when you say it!
Fun fact you can figure out out which tone both the first and surname are in by using these diacritical marks.
Neutral tone - a (no pitch)
So Xià (is the 4th falling tone) followed by Fěi (the 3rd falling/rising tone).
Chinese people usually give their kid a 2 words name or 3 words name. If the words in a first name were both the same tone it’s would be hard to pronounce.
谐音 is a literarily trick similar to how a writer can use homophones in English to symbolize something.
谐音 is when words can sound the exact same but be are spelled completely differently.
“By, bye, buy”
“To, too, two”
“Flour, flower”
“Knight, night”
夏斐 Xià Fěi’s name actually uses 谐音
夏 is Pronounced Xià it means “summer”
下 is also pronounced Xià it means “down”
It changes meaning depending on the word next to it though, but other meanings of Xià still include; Downwards, Under, Below, Descend, Fall, Give birth too, Spate...
'Second of two parts'... guys is it obvious I ship Veinfei
下 is not typically not used anymore unless it refers to very specific instances of time, directions, or positions.
This play on words of Xià and the concept of 下 “down” works in tandem with the 4th tone. And brings us back to the original idea of “the future being below you.” It perfectly relates the idea of time to the name, while also holding symbolism. The future is below Xià Fěi.
Vein's name is first pointed out by @rainibao (here). That Vein’s true name - 萧未影 Xiāo Wèiyǐng relates to the concept of the future!
I’d like to add that 未 by itself does not mean future, but rather it’s 未来.
未来 - Future
未 on its own means “not yet”
Both are falling tones.
Just in case I made this pretty confusing.
I gave Xià Fěi's name as proof to show that he is RELATED TO TIME and related to VEIN. Meanwhile every example of Vein points to downwards symbolism as well.
And even though Xià Fěi should represent Upwards symbolism, the fact that he also represents downward symbolism felt like it does help my case in relate to hindsight as well.
But either way, heres some pretty obvious Upwards symbolism for Xià Fěi too.
This is a post by miyamiwu (here) guys wtf I already ran out of image space
Here with the water
Lu Guang is drowning and falling downwards into the Future
Vein pulls Xià Fěi upwards above water into the past.
Once again it also references unwanted legacies left behind by Vein.
In the end we see the huanting idea of
Vein as a concept of life after death
Xia Fei as a concept life before death
And Lu Guang representing death itself
Thank you so much for listening to my theory! I feel like this theory has revolutionized the way I see these two. Feel free to contact me or disprove or add to my theory. I took like a whole weeks to make this.
Soon I will release the second part of my theory (yes I have more evidence). This time in relation to Liú Xiāo, how he fits into this entire equation, and what his other power may be. And what happens Post-Vein's death.
