Hmm... there's too many... I guess I can mostly relate to Seiichi Yukimura from The Prince of Tennis.
He loves art, and while I myself am not a huge fan of old French painters like he is, I still like antique paintings. He also enjoys making art, the same as me.
If you cut out the things about socializing he likes to do, we both share common interests.
Because I'm a weeaboo and I don't want to admit it, but I am.
