April. A young girl stands alone, acting suspiciously in front of the entrance to a middle school... That girl is Hitori Bocchi, a new first year student at the school. And starting today, she's going to become friends with everyone in her class... hopefully!

"I want to go home with Honshou-san. I want to go home with Honshou-san..." As Bocchi keeps muttering her desire, Nako offers her some advice: "First you need to go invite her."

Aru attempts to save face in front of her friend Hanako Yamada after she accidentally brings an elementary school backpack to school with her. Things become more difficult for her the next day when she ends up wearing a full elementary school uniform. Later, Aru is challenged to a tennis match by Nako, finding it difficult due to all the times she's been skipping tennis club.

After many hurdles, Bocchi manages to get on talking terms with Kako, only to learn that she has a policy against making any friends. The next day, as Bocchi helps Kako clean the classroom, Kako explains that her policy is to prove herself strong enough to live on her own. Meanwhile, Sotoka worries about asking to be Bocchi's friend while remaining as her apprentice. In the end, she decides to focus on her apprentice training to show her appreciation towards Bocchi.

During cooking class, Bocchi ends up having to work with an unfamiliar group of classmates. With some help from Aru, Bocchi manages to impress her group by making them some whipped cream for their pancakes. Afterwards, Bocchi works up the courage to introduce her friends to Kako before asking her to join her group for making curry during an outdoor class. After a successful curry, Kako acknowledges Bocchi's determination to become stronger and declares herself as her rival.
