Any other notes: he is a very emotionally damaged person, though he is really sweet. Much like a tsundere except he isn’t entirely mean to the love interest due to his pure interest and fascination of her. He doesn’t yell at her or hurt her unless she really sets him off. He is very quiet and is often known as the “Bad Kid”. Part of the Yakuza’s orphans doesn’t help him much either in school, since the Yakuza has finally forced him to educate himself. Fears mostly losing his only ‘real’ family and is scared of being alone again. He doesn’t really appreciate becoming the beta male
