From the moment my daughter's friend kissed me...

He lost his wife early, and somehow managed to raise his daughter on his own. Recently, my daughter has been puberty and has been telling me that she's stinking and filthy, but she plays the role of the "ideal father" in order to avoid making her uncomfortable. One day, I met my daughter's best friend, Mai. She was surprised to see her affection for me. Although he resisted at first, he couldn't hold back as a man...and then a relationship began that should never be discovered by his daughter.
