main story - bickering rivals. one of them gets transported into a parallel world, finds out the other loves him and they get together once he comes back. and he and his partner later travel to parallel words and see other versions of themselves.
slight selfcest in one chapter lol. lots of possessiveness
side story - fat dude fetishist x fat barmenas and bodyguard. hot boob stuff but it was basically groping noncon for most of it smh
reread this after a while and overall it's good smut but mid plot. but for the interesting setting and dynamics I'll keep it a 4 (like a 7 tbh)
I'm Banging My Rival From A Parallel World!?
