A record of having sex with a boyish female friend who has a strong personality until the sperm dries up.

Nami, who was once a man, became a carpenter's apprentice. Looking back, I feel like I've always had a strong competitive spirit and always lost in fights. When I returned home for the first time in a while, I saw Nami for the first time in a few years, and she was still the same as ever...but...before I saw her for a while, she had started to look more feminine. What was I thinking? The other person is that Nami! ! Once I became conscious, I couldn't stop, I couldn't control my feelings.
