Although he is the son of a hot spring inn, Takahiro is still a virgin even if he is over 30 years old due to his retreat and thoughtful personality. Yumi Takamine, a childhood friend, came back from Tokyo as a childhood friend and as a Nakai apprentice at Takahiro’s inn. I started working. It’s a chance for a thousand times, but it seems that her return home is quite deep. Is it possible for Takahiro to reverse the Ippatsu of love and fulfill his big wish?
