When she becomes beautiful, I can become a hundred times more handsome at most. Her figure has improved a little, and my mermaid lines have come out. No, I don't have enough time as a friend, so I want to bind a second friend. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
