Shizuku Mizutani is tasked with delivering the class printouts to Haru Yoshida's home (who is skipping school despite having a suspension he obtained for fighting, over). Haru sees this as something only a friend would do and declares that they are friends. Their class teacher, Saeko tries to get Shizuku to persuade Haru to come to school or else he would be expelled. Meanwhile, Haru's punk friends take advantage of his sincerity and use him for money but Shizuku steps in and reveals the truth to Haru. He then confesses of loving her. Haru eventually goes back to school, where his inability to distinguish social protocols causes a wave of bizzare actions. Eventually, Haru nags Shizuku to go to a monjayaki restaurant but she states that she can't because of her studies. Though when he solves her math problem, she has a flashback where Haru had been the top ranked student before he was suspended. Shizuku then deems him her rival and studies hard, eventually places 1st in the midterms.

Shizuku is caught in a whirlwind of emotions and to make matters worse, a new weirdo has entered her life.

An oddball collection students have teamed up to build a chicken coop for Nagoya.

Some simple advice from Shizuku has led to the class thinking different of Haru. Haru and friends enjoy time by the river.

Shizuku wants to know more about Haru’s past, but it is a difficult subject for him. She learns more than expected when Haru’s brother meets her at school.

Still bothered between Haru's interaction with Oshima, Shizuku begins to act more coldly and distant towards Haru while she comes to the decision to solely focus on her studies. Meanwhile, Oshima struggles with her feelings over Haru and her troubles of being an introvert. Haru tries to get closer to Shizuku by asking her out on a date, but while studying, she openly admits to him that she doesn't have any more feelings for him which creates a strain on their relationship.

Haru and Shizuku's relationship keeps flipping back and forth. Haru is now determined to win her over and is getting advice from his new friends.
