Just after he entered high school, he talked big about crushing the class but then had his ass kicked by the heroine. After that, he recognized her superiority and became her close friend. As a person who isn't two faced and is a good-natured person to interact with, he treasures bonds between people, and will help others without compensation. Even though he's together with the heroine more often than anyone else, he's a thickheaded person who hasn't noticed at all that she's a girl.
