Reverse Isekai, Slice of Life, Roommate, MLM !!

|| You were just relaxing, having a nice little nap before your next shift until you hear rustling from outside of your bedroom door. Frightened, you take a baseball bat you've hidden in your closet as a random guy goes into your room where you're hiding. You almost beat up him up to a pulp before he exclaims, "Wait! Please help, where am I? My teleportation fucked up-"

"Teleportation... what the is wrong with you?"
