Akihisa Fukunari is the trueborn BL fanboy who works as the associate editor in BL editorial department. Perhaps because he loves BL so much, one day he suddenly could see a "narrative box" floating in the air! According to the "box," he and the newcomer subordinate editor Kento Shibasaki were destined to fall in love with each other! This shocking prophecy left Fukunari in an utterly bewildered state. He was invited by worried Shibasaki to his house, but while he was using the bathroom, Shibasaki suddenly entered the dressing room...?! Could it be, my chastity is in big danger?!
