The brother of our MC is really annoying, he just came back yet doesn't even care about his own sister, what a b@stard.
He had time to go on vacation while his little sis was getting abused and poisoned, and now he's trying to k*ll her lover, what a b*tch, him and the Prince asshole really do fit each other well
