Reina, a new nurse, recommends that her beloved fiancée be admitted to the hospital where she works in order to find a cure for a serious and incurable disease. As a result of the test, it was determined that the condition could only be treated with unapproved drugs from overseas. The director requests that Reina's youthful body be presented to him in exchange for allowing her to use the medicine for clinical use, although it cannot be used normally. Reina accepts the terms with a single desire to save him, and ends up experiencing an impossible pleasure from having sex with someone she despises.
