Yuuichirou Katou

Ichinose's best friend, he seems to have a thing for Ai but hasn't acted on it. Mina's crazy for him but he seems scared of her after the little incident in junior high. He's been friends with Sou for a long time. He's the exact opposite of Sou, he tends to be more like a gentleman and isn't a playboy like his friend. The reason he's such a gentleman to girls is because of his mother. She's pretty and though she may look harmless she actually has a deadly side. One time, in the manga when they were having a parent teacher conference, Mina's mom had teased him about looking adorable. Of course he had snapped and dissed her. His mom quickly changed from sweet and kind to cold and harsh and warned him about disrespecting women. He falls for Ai and later actually tries to steal her away but he decides to back off a little seeing how much she loves Sou. (Source: Wikipedia)
