Other Characters:


Koeguchi Keiichi:

Maaya's art teacher and first love. A clever, reasonable young man who majors in art and teaches classes at night to help feed himself, albeit being from a well-off family. Keiichi takes a chance and asks out his young love interest, starting up a relationship with him.
Although being calm and reasonable, Keiichi can be a handful, and sometimes Maaya feels like the adult in the relationship. Seemingly uncrossable obstacles and a scholarship tear the two apart.

Machida Kaito:

Aki's classmate, and the one who introduces him to Maaya.
Maaya is hired as Machida's tutor, and eventually a friendly tone grows between them. An open-minded boy who stands by his friends, and generally fails at math.

Eri:

Atsushi's girlfriend for most of his senior year in highschool. Initially the two weren't as compatible as they first thought, but somehow they made it work. A girl who seems shy at first, but is full of energy when you get to know her.

Koyama Atsuko:

Atsushi's younger sister, who has more in common with her brother than she likes to admit.
Had a crush on Maaya when she was younger, but it grew into something like admiration, and she now sees him as more of an extra brother. Instead, she has taken a liking to Aki, who barely spares her a glance.
She is bright and lively, and the owner of a spoiled, fat cat.

Reiko:

Daughter of the florist, with a crush on Maaya. Friend of both Maaya and Atsushi.
