After Reincarnating as the White Moonlight in a Regret Novel, I Stopped Chasing Him

Jia Jibo transmigrates into the substitute for the white moonlight in a regret-themed novel. From the start, the domineering, aloof female CEO forces him to drink a wedding cup with her. Remembering how the male lead in the book turns into a monster after thinking he's been cheated on, and tortures himself half to death, he knows he can't touch that drink.

After barely escaping the wedding cup, he discovers he has four older sisters and a brother who was just recently found.

Good grief, I just escaped a wife-betrayal story, and now I'm straight into a biological son's revenge story.

And after that, there's a Divine Doctor, a Dragon King, and a War God. What am I supposed to do, a lowly white moonlight who's only a substitute?
