Great God of the Stars, Please Take a Break

Gu Dongyu is accidentally hit by a truck and transported into a novel. The System that brought him there says it will take him home once he completes his mission. He wants to return for his little sister and the parents who love him dearly. But when setting up his character, he makes himself a girl.

“Why did you choose to be a girl?” The little white dot of light speaks mechanically, with a trace of confusion.

“I once read a book where the protagonist traveled from the modern era to ancient times. He also changed from a boy into a girl: a male soul in a female body, unable to marry, be married, or love. I hope I won't become attached to that place, because the people I love are still in another world.”
