The Mimosa Confessions Novel Volume 2 was written by Mei Hachimoku and illustrated by KUKKA.

After a dramatic first semester, Sakuma and Ushio dive headfirst into summer vacation. Despite their unspoken agreement to not mention the “incident” that occurred on the last day of school, things get real awkward real fast when they meet up with Natsuki on a trip to the aquarium. She asks them a pointed question: “You two are dating, aren't you?”

The trio will be forced to set their unresolved feelings aside when fall semester arrives—and with it, the annual culture festival. Can Sakuma balance his feelings for both of them in addition to his work on the festival committee, not to mention a starring role in the class production of Romeo and Juliet?
