Bro even has a group chat he's a playboy through and through. Ik at the end, he's gonna end up together with the uke but dudeeee, i just CANNOT trust the seme to be loyal. He seems like the kind of guy to sleep with other people when his lover isn't around. Author, please prove me wrong and make this guy do a 180 at the end of this manga.
