Yin is one of two brothers who share one body, but it just appears to be the white half this time. Yin finds spaghetti funny. He is a kind person who likes to help others, but fights with his brother Yang a lot, Yang being the malicious, loud and impulsive side. The two fight a lot, but still care about each other's well being. His brother Yang tries to do bad things but can't because him and Yin share the same body, but now it's just the white half. Gay for Tissues. Contagious tears.
