I'm on the 9th chapter and so far there's something about Meili that really pisses me off V_V
Honestly i feel the same way. I actually quit this because of him. He doesn't seem to regard other's schedules/time and acts selfishly. I know the seme taking his day of to spend it with him was his choice, but he can't do that everyday to "play" with meili, no matter how emotionally invested he is. Meili only seems to think (for the most part) for himself and doesn't think about the consequences of his action.
I think the reason why meili is characterised that way is bc i think his mum RAISED him to be oblivious so he wouldn't ask about his father too deeply or start to regard the evil lady with suspicion (bc it's obvious to pretty much anybody that the bish is a bish). Like, i think she tried to prolong his state of emotional immaturity till so far. Either that or he's a bit mentally/emotionally retarded.
They look a bit like Aomine and Kuroko :D
