i can't remember how it goes exactly but i'll try:
mc and ml are college students that don't know each other but theyve seen each other on campus a couple of times. ml is the stereotypical popular guy and mc is the stereotypical introvert. i'm not too sure how, but they get a bit closer due to the fact that ml likes to push mc's buttons. i can't remember much after this, but there's a specific scene where mc confronts ml about his tendency to be dishonest with everyone around him and messing around with people's feelings i think? they also do it once in ml's apartment i think. i know this sounds like a generic bl manhwa but i'm hoping this will ring some bells ;;
the main character is an actor who had a bad personality and eventually got acid thrown in his face. i can't remember how, but he dies and reincarnates so he decides to be nicer to people this time. the acid attacker turned out to the sister of an unknown actor who the mc bullied and the mc finds out because he decides to be kinder to that unknown actor by helping him land a role. mc is also being controlled by his company or smth and the ml is the owner of a super big company and becomes mc's sponsor or smth i can't remember. in his previous life mc blackmailed ml and so he avoids the ml in his new life.
it might be two different manhwas i'm thinking of but
i read this one a couple years ago but can't remember the name. it was about a camboy that didn't show his face. can't remember how exactly but one of his coworkers finds out about it and they get tgt. it was short and i'm pretty sure it was a manga, or at least drawn in that style. the camboy had glasses too ^^
can't remember many details, but if this rings any bells please let me know! i've been wanting to reread it for a while :)

ML is the stereotypical popular guy on campus with the cliché 'secretly hates everyone' and this specific scene where the MC confronts ML for being two faced and a jerk is the only scene i remember
i know it's really vague but i really want to reread this one as i never finished it if it rings any bells please send it to me!
