ok its been a while since ive read it but ill see what i can remember
spoilers
in the dads room they js like handjob each other but the manhwa is r15 im pretty sure so either theyll skip it or heavily censor it but the novel does go into detail
dont remember what happens right after ngl but fast forward a bit, mc (seungpyo) falls for jaemin and asks him to be his bf
jaemin thinks hes joking around and thinks its another one of their bets but says yes
mc finds out that ml wasnt actually serious about them dating and gets annoyed and ml realises that he was serious ab them
and then lwk the next bits are all kinda blurry in my head but i js remember that its like "hate sex" kinda, they go at it for a while but this is cus ml falls for mc at this point and mc acts all pissed when he isnt really

PLS KISS ANYWHERE BUT THIS ROOOOOOM
