about the older brother hiding that he found out they share the same father? I think it's for the best. Of course you have the liberty of disagreeing but the way I see it, if he told him, now that they had sex, they can never go back to being brothers nor can they carry on on being lovers. And to the seme's account, he ddn't know they were brothers before they became lovers and when he found out he sent his brother away... It's complicated but I think he did the right thing
I don't remember much since it's been a while but I think that I didn't want them to end up together.
How can you lie to the person you care about so much? It's a serious issue,this ruined the whole story for me.
