The protagonists brother? Oh, pity... He's one of the most interesting and better looking characters I've seen so far...
I'm not disagreeing with you lmfao but I just think it'd be a little strange to starting romanticizing over your own brother...especially considering their current relationship. At first I wanted to but then I was like wtf n o
Edit-I'm not saying there isn't a way, but that's more of a developer question/request
