Boys Be ...

Chiharu Nitta

新田千春

She is Kyoichi's athletic love interest, running for their school's track and field team. She has been Kyoichi's friend since childhood, but she also has difficulty expressing love. Though not in a relationship with Kyoichi, she was asked by Booty if she had a boyfriend to which she replied that "he" wouldn't mind. Okazaki continued his advances to which they spent a night together at a lookout point (though nothing happened between them). She wanted to keep her tryst a secret, but Kyoichi, coming in to visit, saw them kissing, hence a rift between them that lasted all summer.

Makoto Kurumizawa

胡桃沢マコト

He is the epitome of a girl-obsessed guy, keeping an electronic database of almost all the girls at Otowa-no-Mori with him (to a point of bribing some informers to get the scoop), even using computer dating simulators and guide books (actually, he's terribly shy and can't do anything in decisive situations). He is also the only techno-geek in the group. After he botched his date with Erika Kawai, he ended up with her best friend (who acted as the bridge between them), Yumi Kazama. He also had an interlude with a nursing intern after getting hospitalized for peeping at a short-skirted girl as she climbed an overpass, and his scooter hitting a mini-truck, but he forgot about her when he saw that girl again.
