Whether it's pondering blood types or investigating the seven wonders of the school for the class newspaper, Kanata and Kazuki manage to enjoy every day they spend with each other. But with decisions about their futures on the horizon, their mutual affection might not be enough to keep them together...

It’s Kazuki and Kanata’s first ever Valentine’s Day as a couple, though it’s hard to celebrate with the shadow of Kazuki’s departure looming over the festivities. To make matters worse, Kazuki suddenly suggests they take a break from their relationship! With the school year finally drawing to an end, the students of Class 2- b look toward what the future holds as the curtains close on their lives and love at fourteen.

Amid the hormones and the angst of middle school adolescence, Kazuki and Kanata go from being boy and girl friends to boyfriend and girlfriend. But with love comes intense emotions and, with their model student reputations on the line, they must learn to suppress these earnest feelings or run the risk of getting caught red hand-in-handed!

Even with Kazuki’s impending move and Kanata’s broken ankle, it seems as if the two mature students of Class 2-b are managing to take things in stride—but are they really? As they steel themselves for a new chapter in their relationship, Kazuki and Kanata are determined to weather the oncoming storm together…

(Volume 1) The second year of junior high, when most students are in the throes of puberty and feeling the pangs of first love. It's no different for Kanata Tanaka and Kazuki Yoshikawa, a girl and a boy who have been friends since elementary school. But even though Kanata and Kazuki are at the same point in life as their classmates, an air of adulthood sets the two apart. Kanata is taller and more attractive than the other girls, but the boys stay away because she seems too mature for them. Kazuki too stands out from the other boys, but the girls are wary of him because he seems like a player. And so, Kanata and Kazuki are thrown together in a charming, bittersweet tale of two very adult students falling in love like the teenagers they are.

On the heels of the sports festival comes the biggest middle school event yet--the class trip! But before Kazuki and Kanata can worry about keeping up appearances in Kyoto, they'll have to pass their exams. When Kazuki's math skills don't measure up to his--or Kanata's--model-student standards, though, the only person he can ask for help is...Shiki-san?!

Kazuki and Kanata are the two mature students of Class 2-B—and it might be time for their relationship to mature as well. But with the end of the school year and Kazuki’s subsequent move approaching quickly, time is running out. Luckily, a well-timed blizzard during the class ski trip brings secrets, revelations, and a night to remember…
