It is a story in which the protagonist gradually becomes more familiar after experiencing many worlds and seeing many beautiful scenery in the world. He will not deliberately contact or stay away from the protagonist of the original world. The protagonist has his own life.
(There is a single arrow protagonist) (Both male and female identities are available) (Protagonist boss) (No fixed CP)
PS: The first two worlds are not very easy to write and can be skipped without affecting the subsequent plot. The label is made by the system. I will not label ancient romance and no CP together.
