Kai Yi: Are you legit?
System: I am.
Kai Yi: Good. I was worried the world's will would erase me if I didn't do things by the book.
System: ...
World's Will: I only wanted to ask him for a favor, but he ended up ruling the world.
Transmigrator: I only wanted to fall in love, rule the world, or do a conquest, but he erased me.

System: ...

Theme: Everything revolves around shipping couples
