You and I Are Polar Opposites

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...

As their first Christmas Eve together approaches, Suzuki and Tani plan their date. They decide to challenge themselves to make a cake, and Suzuki's heart flutters as she watches how seriously Tani takes everything, and then...

In the middle of winter break, Yamada grows anxious about the fact that his relationship with Nishi just hasn't made much progress. He uses homework as a pretext to see her, but he can't find the right timing to confess his feelings.

Tani tells his family that he's dating someone, and asks Suzuki over on New Year's Day. Flustered by the invitation, Suzuki makes one gaffe after another in front of his family. On the last day of winter break, the usual group of friends enjoy visiting a shrine together. Moved by Tani's words about living with no regrets, each of them step into the new year with hopes and feelings in their hearts.

The new term begins. Taira realizes that he has been under a misconception for years. Suzuki takes Yamada to the school library, with an ulterior motive in mind. Nishi is happy that Yamada came, but anxious that others might find out about their relationship. When Honda asks what that relationship is, Nishi feels absolutely overwhelmed, but with a little nudge, Nishi realizes her true feelings.

Though Yamada wants to confess his feelings to Nishi, he can't find the right timing. The two of them go on a date, and as Nishi turns things over in her mind, her feelings for Yamada swell. She blurts out, "I love you!" Yamada is taken aback by the sudden turn of events, but... Valentine's Day arrives and Suzuki gives Tani homemade cookies, but his too-honest reaction sends her into a sulk.

When Taira hears that Yamada has a girlfriend, he’s able to offer his honest congratulations. Later, in the middle of a conversation, Taira is assailed by his past trauma. After the last day of the school year, Taira and Azuma head to a local restaurant together. Azuma realizes that she doesn’t want to lose her connection to Taira as she, along with everyone else, prepares to face the new season.

During spring break, Yamada and Nishi spend some quality time together at the aquarium that brings them even closer. Suzuki’s birthday arrives, and on a date with Tani, she expresses her anxiety about things to come. Tani's words set her at ease, but in truth, he also feels anxious. For the new term, Azuma and Taira end up in different classes. Azuma tells herself that they’re just friends, but…

Nishi and Yamada spend some time at Yamada's house.

Azuma realizes she has feelings for Taira, and Tani seems down about graduating.

Suzuki and Tani study together to prepare for their upcoming exams.

Azuma realizes she has feelings for Taira but keeps her distance to avoid ruining their relationship.

Azuma realizes she won't see Taira as often after graduation and tries to say goodbye without regrets.
