Seriously

R we reading the same story here u do realize she's not with him out of love r feelings for him right, and that she's only using him for her own selfish reasons so can u really call that a relationship and he's gay to boot so they both used each other from the getgo

That's irrelevant. It's not fair to the younger brother. Because at the end of the day they're not together and he's with the sister instead. Cheating is never a good start to a relationship. He loves him? Then break up with the sister and start a more genuine relationship.

Also on another note, we're not given a proper reason as to why they're together in the first place. It's totally vague rn she may or may not be a total bitch but so far she's not been mean to her brother.

U need to read over the entire thing to c that she's not mean she's just controlling to the point where she stalked her "boyfriend" after finding out the truth about her brother on the night he dressed up like a girl, then not only after knowing the truth she rubbed her so called relationship in his face while forcing him to be around her and her "boyfriend", and like I've said before can we really call it a relationship when there is clearly no feelings from either party and no commitment

Accidentally thumbed down. I agree with you. Regardless of the reason, cheating is never ok. He's very cowardly and need to be upfront about his feelings to all party involved. He's disrespecting the sister and the guy he loves simultaneously.

i agree completely. Take the high road and end the relationship with the sis if you wanna start one with the bro!

She's controlling of her brother, so she deserves to get cheated? What logic is that? There's no feelings involved? Break up first instead of sleeping around! The seme can simply break up with her and pursue the brother, but he's not doing anything. It's plain douchebaggery, like I said the sister being deserving of hatred or not is irrelevant at the end of the day they're doing something wrong. There's no justification for cheating. In fact from another view, the seme's far worse than the sister because he's with the sister while also stringing the brother along, how's that fair to the brother? Two timing is never okay, regardless of if you have feelings or not.
