The only thing Masaru wants to do in life is to help people and dreams of becoming a caregiver one day. He desperately needs an internship and is soon interning at a clinic run by Director Koharu. He can’t help feeling an instant attraction to her, but soon discovers that she runs an unorthodox practice known as Sexual Neurology. He finds himself “helping” the female clients with their sexual problems.

Masaru reluctantly accepts his mission to help all the women with broken hearts that enters Koharu’s clinic, but he finds it increasingly difficult to do so when all he wants is to have Koharu all to himself.
