I actually don't mind Leon. Yeah he's messed up and what he went through doesn't warrant his behavior but I can see his insecurities. Having someone pure would do him good and change him for the better. Just because someone is fu*ked up doesn't mean they should be ignored or dropped. I hope Leon gets a happy ending and changes for the better.
Other than that. I love Chiharu! Best seme ever. He stood against Leon's torment well. Ikumi needs to buck up and accepts his feelings. I hope this doesn't turn into a 'chiharu would be better off without me' thing. I'd punch him.
Update please!
I don't know how to feel right now. I really hope this ends happy for everyone...T_T
