Forgot Sumire and hello to Aoi...

Sumire claims he has no feelings for Yuri at the same time he gets jealous and possessive when anyone wants to date her. He even went as far as sexual assaulting her as a "lesson" for even thinking of a dating a guy who is not him. If he doesn't want to be her with that's fine. But don't give mix messages and claim you own her when you ignore her feelings.

I'm rooting for Aoi. He was the only one who literally throws himself at Yuri and even begged her to chose him. And yes, they're half sibling but you know what's even more digusting?

Sumire's bull$hit. "I want you but I can't cuz I still love Seri... wah wah wah". That bit*ch is dead. Move on.

I think the problem here is Yuki is chasing after a person she can't get while ignoring the only person who is literally begged her to pick him.

*Rant over*.
