unlikeable character in the 2nd volume. There's nothing that endears you to him. It's almost like the MC has Stockholm syndrome...
Cos other than that I
really can't understand WHY he puts so much effort to get Hachi's attention back.
Dude, after doing soooooo much horrid stuff, then CHEATS on him?!!! Like WTH? Then goes all caveman on him at the slightest bit of (
overdue) rebellion [which is even faked] to get him back.
...Like

MC have some self respect.
RUN THE FUDGE AWAY! Dude is a major fudge boy!
