Hisashi Uehara

A popular and good-looking guy, and unsurprisingly has a bunch of fangirls. In fact, he made the school's "Top Three Hottest Guys" for three years in a row. He lives together with Nao because of the whole renting fiasco. He's very aloof and antisocial, and gets straight A's without studying. Because he is very mature looking, he is commonly believed to be older than he looks.
