Boku ni Hitsuyou na Mono

One winter night, in a dormitory room, Wakana and Futaba are forced to share a blanket to keep warm while studying because the heater has broken down. When Wakana asks Futaba if he wants to try having sex, Futaba cannot refuse the eager Wakana and finds the touch pleasurable. However, embarrassment causes Futaba to flee the room.

Futaba feels distressed, unsure if Wakana's advance was a joke or mere curiosity. As their relationship, which began as a sexual encounter, develops, Futaba struggles to understand Wakana's true feelings and intentions.
