!not proofread!

you squirmed under rin's intense gaze. he was pissed pissed. the safest thing for you right now was to keep your mouth shut.

rin was waiting for you at your apartment when you got home from your little nap with sae. you were kind of regretting giving him the spare key to your apartment. but you knew that this would have to be done one day or the other. you just didn't know that it would be this soon.

with the last bit of courage, you looked your best friend in the eyes, "rin-"

"don't" he cut you off before you could even explain yourself.

it's kinda stupid, he thinks. he has known that his older brother has harbored feelings for you for years, but never acted on it because sae believed that relationships are a waste of his time.

now, rin wasn't stupid, he very well knew that all that happened between you and his brother could have been the result of the alcohol in both your systems. he just couldn't accept it.

what annoyed rin the most is that he doesn't know if sae took advantage of your drunken state. deep down he knows that his brother is better than this. and no matter how much of an asshole he could be; he would never stoop to that level. but, he can't think straight right now. what if there's even a slightest of the slightest chance that this was all planned by sae. he would make sure to make his brother's life a living hell.

"whatever you're thinking, it's not that," your voice pulled him out of the spiral of thoughts in his head. he looked at the couch you were sitting on. what was this? some kind of intervention? in your own house?

you gulped, before continuing, "i don't remember much from last night. it's all a little blur, to be honest. but i was the one that initiated the kiss that led to all of this," you vaguely motioned with your hand, "i remember a few moments here and there. your brother didn't force himself on me."

"do you love him?"

you choked on your own saliva. where the hell did that come from? "well...." you paused, trying to find the right words, "'love' would be too strong of a word." he didn't say anything in return. an uncomfortable and tense silence settled over you two.

"i do like him!" you blurted out. you had to say something, you couldn't take the silence anymore. looking down, you fiddled with your fingers. "i like him," you reiterated, "a lot. and i would like to give him a chance."

rin sighed. he knew this was coming but seriously? his best friend and his brother? it would take him some time to accept it.

"we discussed it...before he dropped me off..." you trailed off, "he wants to court me. officially."

"okay."

"huh?"

"i said, okay" his irritated tone made you shut up real quick. right, he hates repeating himself. and if it were someone else, he would have ignored them a second time. they weren't worth his time. but you were his best friend, you weren't someone else. as much as he hates it, he would repeat himself for his best friend; and how do you pay him back? by sleeping with his damn brother? he scoffs at the thought.

honestly? he should've seen this coming. he knew your lingering gazes and exchanged glances would lead to something someday.

he sighed for what seemed like the millionth time. he can't do this right now. too much thinking. so the both of you spent the rest of the evening watching horror movies.
