One year, on the 14th of February, the protagonist has gone from being a dull virgin to a fiercely popular guy, but because of a minor secret about his pubic area (which would be embarrassing if exposed), he can't have an intimate relationship with a girl even if he wanted to. Then a magical girl who claims to be the "Goddess of Hair" appears and offers to perform a ritual that will solve his problems in one fell swoop. The protagonist agrees to the offer, but for some reason the only condition for success is that he has to spend one more month without letting anyone know the secret of his small genitals. In other words, until the 14th of March, when the ritual is to be carried out, he has to live a pure and innocent school life without revealing the contents of his pants to the heroines. Will the protagonist, who is exposed to unrelenting pheromones and must never surrender to the flow, be able to survive these heavenly hellish days?
