After becoming friendly with her on set, the production company obtains her phone number. After filming, they immediately contact each other and head off on a trip to a hot spring just the two of them. Of course, the purpose is not the perversion she always shows on set, but to reveal her true feminine eroticism when they are alone together. A private hot spring, a luxurious hot spring inn, and meals. An intense time spent together in an intimate atmosphere just for the two of them. And at the end, her true sexuality is revealed as she engages in sex without makeup.
