Yoshie is an extremely cheerful high schooler. He regularly visits the chiropractic run by the father of his friend mikawa. Mikawa is quiet and emotionless, but popular with the girls. Rumor has it that he tells girls he’ll teach them about chiropractics, then drags them into his room… Because of that, Yoshie didn’t really like Mikawa all that much, until one day, he ends up getting a massage from Mikawa! And right after the massage starts, he says “I want to tease you a little!” This is a slightly dangerous youth love story!
