If not canon, then why flashy?
Eyesex and a smile?
The guy that hates physical contact is smiling as kohaku hugged him? Not only that but he also looked into her eyes tenderly? LIKE? The other girl going "it wasn't that type of hug" was just referring to the fact that they aren't gf and bf because technically THEY AREN'T and the one girl still assumed that they were. So when they got touch- feely and the girl covered her eyes thinking they were a couple(thanks to the kiss situation) the other girl calmed her down saying they weren't really a couple sharing a hug; but two people that care about each other hugging. While Senku did not return the hug because he is never/and has never been forward about that type of situation, Kohaku is the first he's smiles at, lets hug, and has had people wonder the state of their relationship when being hugged by. She is also the only girl he is close with, that has been hinted at having feelings for him.
The KISS
Sorry, No I get it. It was too soon for this to be a romantic moment. I get it. It was for the sake of comic relief. But if you pay attention. The context of the scene didn't necessarily have to be written romantically, NOT EVEN for the sake of the plot. Cause them kissing had nothing to do with the situation; BUT the mangaka STILL specifically chose to go THAT route with the scene. He, HIMSELF, chose to use a romantic excuse(even if a comical one) as a plot device to move the story forward. And on top of that made them kiss(even if they were both uncomfortable by it still at this point in the manga). With that, making Kohaku the girl he's closest to who he has had the most physical contact with and even shared a kiss with(even if it was just a chin kiss and they both were practically uncomfortable for being forced to do.). No but seriously, the mangaka using SenHaku as a plot device to move the story forward WHEN it is NOT needed should provide some insight of what he thinks of the pairing. Which is that: "it is fun to write about" and "he likes to write about it".
NO TIME?
I like how he reponds with something that implies. "Maybe i'll blush later....not rn we gotta find a way out of here". Can we also take a moment to realize the mangaka/writter interrupted this moment before Senku could respond to the: "and the way i see it that is so very-" from kohaku? Subtle behavior on his part. Is there something on Senku's mind he doesn't want fans to know for the sake of avoiding ship wars? I wouldn't be surprised if this was what was stopping him from making the ship more explicit. Cause shippers get kind of crazy with the wars and MOST mangakas KNOW this and dont want that to affect the sales.
BRIDE STYLE?
He specifically chose one of the most romantic tropes to draw them In? Sorry no. This has nothing to do with their dynamic; but he still drew them like this? In THIS pose? Mangaka definitely shipped them.
Nah; but like never have i ever seen him so touchy feeling with anyone?
idk idk they remain sus. Especially with all of his guy friends hoping him to experince romantic love.
SenHaku also kinda parallel His adoptive dad and his lover(maybe not in the sense of dynamic; but in color aesthetic and how they are portrayed in the covers)
[also look at them being bride style like the senhaku cover lol]
I don't know why people say this ship is impossible because Senku says he isn't interested in romance. Like he also hinted at the fact that he has sex drive, just not a crazy active one where he would attack a female for, especially one stronger than him.
And if you ACTUALLY pay attention every time that topic of romance comes up is not that he COMPLETELY dismisses it. It is more because he does not prioritize it or care to look for it, especially considering that he is so goal-driven. At the same time, it is already revealed that not everything he says(especially when it comes to relationships/bonds)does he mean. He only, like i said, likes to remain goal-oriented and doesn't want anything to distract him.
He also acted pretty detached towards his own father and rejected his overly affections of love. So much so, that Byakuya tried to adapt to his own love language of science. But at the end of the day,it is not that Senku is 100% against those concepts(of romanticized bonds) it is just that he finds them to be waste of time. But despite that, he is still human. He still feels despite how much he doesn't allow himself to do so:
And Riri herself pointed how Senku only acts tough and detached when it comes to relationships/bonds(when talking about his care for the village) but a part of him does care. This is because she is the only one whose seen him cry at his father grave, despite how detached he acted about his father dying at the beginning. But again, he remembered that he had a goal, and wiped his tears; because for him "there's no time for that". It's all about prioritizing his goals, especially when about science.
And there's ALOT of emphasis on THAT.
Even so, so many characters in shounen have ended up marrying/having feelings despite saying/or there being no indicator that they are interested in romance. It is a common trope of it. So even if it were because Senku is not into romance it wouldn't sink the ship. I mean look at Sasuke(another goal-oritented character) said that romance had no place in his revolution; but at the end of the day married sakura and even gave her a ring to ward off insects
[note: is important to note that sasuke was not rejecting sakura here. More like trying to convince kakashi that romance had no place in his revolution. Because he was goal oriented, like Senku(that and the fact that he was still struggling with his darkness). In fact Sakura said that she wanted things to go back to the way they used to be and he assumed that was romance, without anyone saying anything of that sort. And Sakura had already left it clear that she wanted team 7 back; but then sasuke mentioned romance lol]
------------------------------------------------------------------------------
Something else worth mentioning is the fact that Senku hates clingy overly-romantic girls or the girls that fall in love too fast with him, as we've seen him cringe or act annoyed with those type of acts. But still, he was able to manage to say something about a type, despite his dismissive behavior. Even tho it was just to brush the conversation off, the fact that he answered his type of girl with "someone that could bring him materials" and then calls Kohaku a lioness, and him as a scientist knows that usually a lioness is one to provide their mates with food from hunting. I don't know. It seemed like a sweet nickname to give her. Especially when in his time period, that type of nickname is considered flirtatious. What is more, is that he initially brought Taiju back because of his usefulness in strength(and the fact he knew he could trust him) & Senku himself noticed the exact same quality in Kohaku.
So someone that could fit his description of his type would definitely be kohaku and seeing that she is the girl who he is the closest, and HAS brought him materials before so i dont see why not. I mean he was already pretty impressed with her first meeting her. Even after having worked with her, he was still impressed by her strength, and doesn't stop talking about it:
There's also people who always dismiss Kohaku's feelings. I mean i think it's already pretty clear
His physical aspect she seems pleased with
And well he already fits the EXACT description of her EXACT type. So it is 100% safe to say that she has feelings for him. It may not be explicitly stated but it was just the right amount of sublte. Similar to Mikasa Ackerman/Touka Kirishima, whose feelings were never explicitly stated; but were always quite obvious. That was the type of subtlety the mangaka was aiming at. And i think there's a reason for that.
Because Senku hates fast paced relationships/love at first sight/mushy girls. Building Kohaku's feelings in a slowburn manner makes Kohaku stand out from all the other girls that have feelings for him/have flirted with him/felt attracted to him. Because, as i said, he doesn't like that kind of stuff. And since he is still sciency I don't think he would ever fall for a romantic type of girl; but rather a useful one that can serve as his partner. The way I see them happening would be by Kohaku being accepting of his anti-romantic nature, and Senku seeing her as worthy Mate that he could reproduce with so that the sciene can live on and keep developing. While he did teach Chrome alot, Chrome also says he wants Senku to live. I think he also meant it in a metaphorical way. Chrome, next to his other male friends kept pushing for or looking for an indicator of him feeling attraction for a girl/or at least want him to understand romantic love so that he doesn't keep downplaying the feelings that they have towards their crushes. Even Gen seemed pretty excited at the thought of him kissing a girl lol. So it's safe to say that the mangaka writing this was him rooting for the same thing for Senku; but not in the way that we exepect.
Again, if he ever did develop a relationsip with kohaku to another level. I dont think he would confess/or admit his physical attraction to her, if he did feel any. I think he would find himself content that he has found a useful girl, that can bring him materials, and doesn't ask much of him(in a romantic light). This would push Senku to allow Kohaku as his partner. I don't think Kohaku would mind it either as long as she knows Senku is willing to reciprocate in terms of just the right amount of romantic gestures/or sexual entanglement(when senku finds the time for her)
Because as he has stated he does not NOT have a sex drive(just not active) nor is he COMPLETELY against chivalry (which is rooted in romance).
So i think if he did develop feelings for Kohaku he will not do much to figure out the why and would instead only try to rationalize it by saying Kohaku is the perfect partner. He would agree to a wedding for the sake of his friends and act like he was peer pressured to doing it, and would probably ONLY compliment Kohaku's looks by saying something like "You know, according to the symmetrical proportions of your face, you'd be considered to be living up to the beauty standards of my time" and Kohaku would be fine with that thanks to the reassurance of her sister about how "he is not the type of guy to be completely against the tradition of bonds/feelings. He just doesn't prioritize them". So kohaku would be fine with that. Especially because she herself has been swayed by his way of living.
As long as she knows that Senku considers her his mate, partner, and important person, I think she'd be okay with that. Especially since Senku is logical enough to understand that he needs to put effort into the relationship with his mate. So he'd do soft gestures for her that will keep her happy in order to maintain their relationship, even if she doesn't ask for it. And that will be enough because by the end of the day that's what most relationships are, Senku just doesn't feel the need to romanticize them, unless it's for the sake of following through with a logical situation. And well him maintaining his relationship with Kohaku would be logical as it would avoid conflict and prevent him from seeking a mate elsewhere. We all know Senku doesn't like to bother with those things. He just goes with the flow of whatever is convenient.
I also think that even though he doesn't like physical contact he'd probably do soft things like touch her hand in reassurance,(he's held her hand), smile at her(as he has done so before), look tenderly at her with pride(has looked and felt proud of her) and lean on her when he is tired(they have leaned on each other metaphorically). Those would be indicators.of him caring for her, but he won't ever stop to think about them, even if his heart rate actually does start to raise he will only rationalize it with talks about "dopamine/serotonin" and Kohaku being his chosen partner; but overall, he'd be most ecstatic about having a partner by his side, and the fact that he cares for such partner. Kohaku won't ask for more and will come to understand that she has what any other girl has(when it comes to romantic relationships), and she SIMPLY has a partner that tends to rationalize everything and dislikes romance; but is willing to do it for the sake of logic.
