A/N: This is the first time I’ve ever written a sibling au, so this is exciting! I would love to have Yanjun as an older brother tbh. Happy reading!
oof can you imagine yanjun as your older brother tho
i can only imagine he’d be two things
you and yanjun shared the typical sibling relationship
which means constant fighting and teasing from both parties
the two of you can’t go a day without being at each other’s neck tbh
1 like = 1 prayer for your poor parents who have to go through their kids bs everyday
normal occurrences usually go like this
“yanjun don’t eat the food that’s in the fridge”
“oh, you mean the three slices of pizza on the top shelf? too late lmao”
“lin yanjun istg i will eND YOU”
“get lost, loser. why would i give you my hard earned money?”
“oh, ig that’s fine. in that case, you wouldn’t mind if i told mom about how it was you who knocked over her favorite vase but blamed it on the cat instead, right?”
“slide in an extra $10 and i also wont tell her that it ocurred the same night you snuck out to zhangjing’s party”
“LIN YANJUN GTFO OF THE SHOWER! IT’S BEEN TWO HOURS AND I HAVE TO PEE”
ofc things weren’t always so bad
usually when hell freezes over
yanjun and you had this sort of ritual where he drives you both to the nearest fast food place at two in the morning once a week
it was your way of bonding with each other and what better way to bond than over food?
yanjun was also your own personal chauffeur and drove you around his fancy motorcycle whenever you needed to get places
this idiot named his motorcycle angle angel
in return, you often helped sneak him into the house whenever he was out longer than he was supposed to
you joked that he was going through his rebellious phase
except that it occurred 24/7 365 days a year
one time he tried to climb in through your bedroom window at 4 in the morning
you almost dialed 911 on him bc you thought he was an intruder
in short, you both had your moments where you actually got along for once
unfortunately, this was not one of those times
you angrily stormed into your older brother’s room, slamming his door open as it hit the wall with a loud bang
“what the hell is your problem? can’t you knock?” yanjun glared, removing his headphones off his head
“cough it up,” you demanded, holding out your hand impatiently
“what are you even talking about?”
“my watch! the expensive silver one that dad gave me for my birthday”
“look (y/n), sorry to burst your bubble but i don’t have your watch”
you raised your voice in anger, “stop lying! i know you stole it from me after i saw you eyeing it the other day”
annoyed with the accusation, yanjun’s glare intensified and his voice yelled back even louder, “i didn’t steal anything, idiot! maybe if you learn to be more responsible, you’ll stop losing things!”
you groaned in frustration, flipping him the finger and stomping out of his room. you didn’t have time for this.
after the fight, you were running late for your date with your partner who you’ve been seeing recently
when you arrived at the restaurant, you were shocked to see your partner in the arms of another person. you watched as the two of them exchange kisses with their arms wrapped around each other
*insert ‘oh hell no’ vine here*
you marched your way over to them, picked up a glass of water and splashed it all over your partner’s face
they were obviously a v thirsty mofo
the entire restaurant went silent bc oh shiiiiiit
somebody call worldstarhiphop
“you cheater! you make me absolutely sick. we’re over. i deserve a lot better than your sorry ass” you scowled
the entire restaurant literally broke out into applause and whistles for you
wow where can i get that kind of support
even with the cheers, you were understandably still really pissed
huffing, you walked over to the nearest bus station down the street
you cursed when you realized you had just missed your bus back home and the next one wouldn’t be for another hour
rummaging in your bag for your phone, your fingers grazed against something cool
pulling it out, you realized it was your silver watch that you had accused yanjun of stealing earlier that day
a wave of guilt washed over you
not only did you get cheated on but you felt like the world’s shittiest little sibling ever
scrolling through the contacts on your phone, your thumb hovered over yanjun’s contact name
you debated whether or not you should call him to give you a ride. both of your parents were at work and you knew he was still most likely at home at this time
but would he even pick up your call?
after a few seconds of hesitance, you settled for texting him instead
you: they cheated on me. please take me home.
honestly you didn’t expect him to text you back since he usually needed time to cool down after fighting. you mentally prepared your self for the long walk home.
to your surprise, yanjun immediately texted you back
the adopted sibling 🙄 : stay where you are. i’m coming to get you.
after texting him the details of your location, it didn’t take long for him to show up on his noble steed motorcycle. offering you a small smirk, you returning it with a small smile. he tossed you the spare helmet and you strapped it on before hopping on behind him
the two of your drove in silence but not necessarily an awkward silence. it was more so yanjun not wanting to force you to say anything until you were ready. you were also trying to wrap your mind around how hectic this day was.
“yanjun? are you still mad at me?” you asked when he stopped at a red light
“mad at you? nah. i’m over it. your ex? i’m going to kill them” he replied
you smacked his shoulder, rolling your eyes with a snort as he pretended to wince in pain “if you end up in jail, can i keep all of your things?”
“wow i go through the lengths of getting revenge on your ex for you and all you care about is keeping my things? i’m no star student but i’m pretty sure that’s not how it works”
you grinned, “in my world it does”
once he started driving again, you started to notice you both were going in the wrong direction
“hey, i know i’m not the best at directions but i’m pretty sure we just missed the turn to our house”
“that’s bc we aren’t going home. we’re gonna go to our favorite diner so you can eat your weight in food”
“i do not– ok you know what, you got me there”
being the awesome older brother he was, he let you order whatever you wanted on the menu and even paid for it all. he saw you were still a little down, so he even tried to make you laugh by telling you more of his lame jokes
which honestly made you want to cry more than your break up bc his jokes were so bad
when will he ever learn tbh
“i’m sorry for accusing you of stealing my watch earlier today. you’re right, i should be more responsible with my things,” you apologized sheepishly, poking at your ice cream sundae
“don’t worry about it, kid, it happens. you’re definitely more responsible than i am. that’s for sure,” he chuckled, leaning forward to steal a scoop of your sundae
“woah buddy, hands off! you have your own!”
“yours looks better than mine!”
“we literally have the same order!”
and so you both went back to being the bickering pair of siblings we all know and love
the next time you saw your ex, you saw them freaking out from their car being towed away
was your eyes deceiving you or did you see slashed tires?
when you went to question yanjun about it, he acted as if he had no idea what you were talking about
“bro, what did you do to my ex’s car?”
yes you’re big brother was hella annoying
and yes he did drive you absolutely nuts
but you knew that at the end of the day
you knew that you both loved each other
you would always be there for him
and yanjun would always be there for you
i dont have any brothers irl
i wouldn’t mind him being yanjun tbh
