The Boys’ Dorm Group Transmigrates into a Dog-Blood Novel

You’ve transmigrated into a book, and the system’s only function is to provide you with a group chat with four people.
Your bunkmate, a rough straight guy, has become the submissive in a scumbag-dominant literature.
Your upper bunk, a delicate little zero, has become the scumbag in a chasing-wife-to-the-crematorium literature.
Your roommate, a sunny rich guy, has become the phoenix man from a remote village.
And you, you’re just a background character.
Hahaha.
Ridiculous.
[One person transmigrating is a winner takes all, four people transmigrating is like letting four lunatics roam freely in the vast world.]
