I Heard from Her Friend That My Childhood Friend Girlfriend Is Cheating

One day, Ibuki Takada is shown a photo on his girlfriend Mizuki Yuge’s smartphone by her friend Iida Maya. When he sees her walking with a smile and arm in arm with another man, he begins to wonder if she is cheating on him. Worried about what to do, Ibuki turns down Mizuki’s invitation to go home together, and asks his reliable friends in the literature club for advice, but to no avail. Deciding that the only option is a direct confrontation, he decides to have Mizuki sit across from him in the classroom after school and confront her.
