from what i saw from the last panels, i think the younger twin knows about his brother's feelings, but he doesn't wanna confess because its already too late and he's afraid of changes in their relationship now (like every yaoi's reason for not confessing) he smiled when he saw his brother because he's happy that they had the same feelings, i think there's some psychological case for the younger twin that no one knows. Its like he never wants to confess because its too late, and he intends to make his brother jealous and even making him think that he was just a very understanding younger twin, but deep inside he's also hurting because he cant confess and he knew he's brother and both of them are already hurting.
I've said a lot lol, anyways dont judge its just my theory
its just weird how she's saying she isn't that shiny or anything special but the fact that she's having two men at the same time isn't called confidence? i mean, the she flirts at them then downing herself is confusing, she doesn't have a deginite character i think, i wish she could develop those things herself. its better if she's more aware of what she'd doing, why have no reason for having two men? u could just say that your attractive to both of them yet she's questioning it like she's innocent. im sorry if this made u guys offended, im sorry and im only sharing my opinion.
