I know everyone feels bad for Itsuki and I do too but I think Ai-chan is in a sadder situation. I mean he really seems to love his brother and I see no chance of his love becoming mutual. He also cares about Itsuki but he can love him as much as he loves his brother. And he's stuck, there's nothing he can do. Either someone is going to come and help him move on, or he's gonna go mad.
