He had an ex-girlfriend, and his ex-girlfriend had a best friend. The two women sang along and made him angry.
The perspective will be switched. The story will be told from the perspective of the male protagonist at the beginning, and then it will be told from the perspective of the female protagonist. The heroine's best friend is an important role (an important supporting role).
***Adapted from real events.
Intention: The pseudo-human incident that happened to me is very weird, but I can rest assured that the ending will be satisfying.
