Love Condition Until I, who have never known love, fall in love with you

"I don't need love..." Ichimiya is conditioned to be incapable of kissing due to a traumatic experience in the past. He has never involved himself in a deep relationship with anyone, but when he wakes up drunk after a company party, he finds his colleague, Miyama, who is known as the perfect man. Unlike his unsociable self, Miyama, who took care of him, is popular in their company. He is good-natured as well as a good worker. But then, Miyama asks him to "put it in me". Ichimiya ends up losing his virginity to the sexually frustrated Miyama. Miyama also proposes to help Ichimiya improve his condition. Ichimiya refuses, trying to keep Miyama away, but as he gets involved with him, he finds himself becoming attracted to Miyama?
