Yesssss
All thats gonna happen is that suddenly he'll know he has to figure out if he wants to date you or not instead of the vague "what are we"
There's no way he straight up rejects you so nothing worse than rn?? Eunho kinda frustrates me Yeah Hyeon's a jerk and oblivious but he's trying he just has no frame of reference of comparison aside from "friends" how do you expect him to gain enlightenment (having auadhd, Hyeon is quite relatable)

omfg YES YOU CAN ASK HIM IF HE HAS FEELINGS FOR YOU!!! Holy fucking shit the most frustrating thing I’ve ever read. Like you know the man is a fucking dumbass and don’t understand human relationship so PLEASE JUST TELL HIM
