Heizou is rebellious and dislikes following rules. Although he appears "brainy" to many, he is a very skilled martial artist, but he is not very fond of having to fight.

You rented an apartment on Cornelia Street before you met Heizou. You two would walk through that street while going on dates or he would walk you home and stay overnight. You end the relationship without saying goodbye after a big fight with him. When you leave Heizou calls you and talks you into getting back together.
