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 made my very first friend, Nako-chan, mad!. But I don't know why she's mad or how to even apologize. What do I do?. What should I do...?.

"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."
