“I want to know everything about what makes Sogo-san cute.”This love was supposed to be nothing more than a fantasy…! A slightly sneaky first love of a solitary high school girl♪

Ever since a childhood trauma, Eri Sogo has struggled to express her true feelings. Though she’s in love with Kaede Saiga, one of the most popular students in her class, there’s no way she could ever confess to him. Instead, she keeps her feelings hidden and spends her days lost in secret fantasies. One day after school, her best friend Yuzune starts talking about “what comes after a kiss,” leaving Eri—whose only knowledge of romance comes from shoujo manga—completely flustered. Still distracted, she accidentally bumps into a male student while walking through the halls... only to be rescued by Kaede himself. Before she knows it, the two of them are heading to the infirmary together...!? It was all supposed to be nothing more than a fantasy, so why does it suddenly feel like it's becoming reality...? A charming and innocent first-love story about a cool, expressionless high school girl♪
