spoilers till S1 finale

yeah read the raws and basically their last date - 5th time meeting is at an amusement park etc when
MC drops ML home he's considering to confess but before he can even do that ML (purple hair) starts banging his head on the wall until it bleeds saying what else do i have to do, is this our last time meeting e/o etc stuff like that n then MC kinda gets that he's been playing with him and tries to run away then ML grabs him by the collar n pulls him inside his house where MC asks him if he likes him and the ML repeats the question back laughing and MC starts crying and they basically do it and at the end (this is season 1's finale btw) ML says i'm never letting you leave me :: ML also basically says that his head has been filled with MC and imagine if they didn't coincidentally meet at the beginning etc but yeah
