Season 1

Suzuki is always cheerful and energetic, but she often worries about what the people around her think of her. That's why she secretly admires Tani, the quiet boy who sits next to her in class, for always clearly speaking his mind. One day after school, the two of them end up walking home together, and then...

After their confessions of love are successful, Suzuki and Tani begin dating. Suzuki wants to impress Tani on their first date, a date she's wished for for so long, but she feels like she just keeps spinning her wheels.

Knowledge of Suzuki and Tani's relationship slowly spreads through their class. When Suzuki calls Tani "adorable," it leaves him feeling unsettled and wondering what she means by that word.

Suzuki organizes a study group for their end of term exams. She's happy to see Tani is growing closer to her friends. Then, at last, the day of the summer festival arrives.

Yamada is touched by the shy, reserved Nishi's smile and gradually becomes interested in her. He decides to jump right in and say, "Be my friend!" Little by little, they grow closer.

With the close of summer break, the culture festival arrives. Suzuki reunites with Rihito, a boy she dated in middle school.

After the culture festival, an undefined sort of atmosphere hangs between Yamada and Nishi. Suzuki notices and begins plotting. Tani finds himself left at the mercy of the situation.

The culture festival is over and the season turns to autumn. Azuma is troubled by a message from her ex-boyfriend, and Taira defends Azuma's feelings in her stead. Little by little their relationship is changing.

For Tani's birthday, he and Suzuki go on a museum date. Despite being struck with crowds and other trouble, they express their feelings to each other and grow closer.

At last it's time for the class trip. The girls in her class pelt Suzuki with questions about her relationship with Tani. Suzuki confesses her true feelings to Azuma, saying, "I want to take things further with Tani."

On the second day of the class trip, Nishi gets a message from Yamada saying "I want to see you." She heads out and finally realizes her true feelings. On the last day of the trip, Tani and Suzuki enjoy their time at a theme park, but Tani stops her from leaving and says, "I want to spend a little more time with you."

As the seasons change, Yamada and Nishi become more open with each other, and the negative aura around Azuma and Taira continues to soften. Suzuki and Tani go on a date in Yokohama, and the chance for their first kiss finally arrives, but...
