On the first day of school, Ryūji discovers that he and Taiga, the meanest girl in class, share a secret: each loves the other's best friend.

Taiga has a photo album full of blurry pictures of Kitamura. Ryūji offers to snap some pictures of him instead.

Yūsaku's childhood friend Ami, a model, transfers to the school and immediately becomes popular with everyone but Taiga, who sees the truth about her.

When the school's pool opens for the summer, the gang shops for new swimsuits, and Ryūji helps Taiga with an embarrassing problem.

As preparations get under way for the school's cultural festival, Ryūji urges Taiga to consider reconciling with her estranged father.

Taiga's reconciliation with her father divides her friends, but she ends up disappointed when her father doesn't attend her school play.

A rumor starts that touching Taiga leads to good luck; Yūsaku gets some interesting news from the student council president.

Yūsaku has a meltdown in class, dyes his hair blond and refuses to run for student council, causing everyone to wonder what's wrong with him.

With Christmas approaching, the student council plans a party while Taiga decides to curry favor with Santa by playing Cupid for Ryūji and Minori.

The entire class pitches in to assemble an artificial Christmas tree with a glass star, but a stray fly ball destroys the decorations.

The love triangle of Ryūji, Minori and Taiga reaches a crisis point when true feelings are realized during the school's Christmas Eve party.

The class trip to Okinawa is canceled, leading to a last-minute change of plans to a ski trip, where Ryūji resolves to tell Minori how he feels.

During the ski trip, Ryūji confesses his feelings for Minori, but not to her. When Taiga disappears, everyone frantically searches for her.

Knowing that Taiga believes she was rescued by Yūsaku during the ski trip, Ryūji asks Yūsaku to pretend that she's correct.

When Yasuko collapses from anemia due to overwork, Ryūji and Taiga take over her job of selling chocolate and use Ami's celebrity to improve sales.

When Yasuko reconciles with her parents, the truth about Ryūji's father is revealed, inspiring him to have a traditional wedding with Taiga.
