Ryuji Sakamoto. Bro is a bit of a hothead, but I'm incapable of getting angry, so I would be able to calm him down, and we could chill together. Seems like he's hella mature when it counts, and is an epic gamer. So... Not a crush, I guess, but it fits the description you said well enough.
Uhh, I am a male dom, though, sooo.. I will also say Makoto Niijima, same franchise lol
She is chill and mature, and she would be someone that's cool to bond with. No promises we're remaining only friends, but, you know. :P
