Almighty Female Mentor

He accepted the fact that he had time-traveled very calmly. The current world is a parallel world, and there may be many works that have not appeared, and he time-traveled to a female dance teacher who was about to be abandoned by a scumbag, wearing a man's body and a woman's! Although I accepted the facts, what would the story be like? What kind of sparks will happen between a female protagonist and a male protagonist who is liked by someone without knowing it~~ This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
