I feel like it can go two ways. 1. He has a problem with koko and wants to play with him now that he's fallen for someone or 2. This is a warning from past experience, koko plays around with whoever he finds interesting and when the other party gives in(Falls in love with him) he loses interest and leaves them.
Agree (๑•ㅂ•)و✧
I’m gonna say it’s probably the latter, being that Tomo-Chan told Amami what she did in the past chapter
A good one if they're friends of a person like Hachidori. T.
I mean, what kind of friend says that to their friends lover, unless he has a problem with Koko?
