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
that's just creepy, i mean she went inside like a bitch then now she's asking him where he's going when the wife is clearly in front of them? wtf, she looks cute but imma kill her without a doubt
