In the summer of his second year of high school, Maki Sonoda had sex with a man for the first time. Held in the sweet embrace of his cram school teacher, Shirai Haruji, whom he approached out of mere curiosity, Maki thinks, "I want to do this again. I want to know more about you, Haruji." However, when Maki realizes that Haruji's own yearning is connected to his high school teacher, Mizuguchi, gradually, complicated feelings start to circulate. In this cycle of "boy's love" narratives, the feelings of three people that can't be put into words become heartbreakingly intertwined through sex.
