Yes, it's true! You should never marry a man with two ducks...
I'm kidding. It really is a story about two *cough* *censored*.
I non-literally translated the summary:
This is the story of a person who transmigrated into a world with a radically different worldview.
So different, in fact, that he is considered a female in that world!
Cheng Nuo: What? Why did you say that I’m female?
Author: You only have one Tintin. The males of this world have two Tintins.
Cheng Nuo: No way! My hands are itchy… I want to cut one off!
This is a 3P, “dog blood” (a little cliche), HE (happy ending) story.
