This has an ML who couldn't seem to give a f*ck about our MC because he was being restrained by the author of the novel world. You'll hate him for giving MC to his friend for one night, to which the MC happily complied but outwardly couldn't show due to character break.

But once ML confesses to our MC, the restraint breaks, but MC broke up with him (that was the main motive) he was depressed for 2 years but once he comes to know about how MC actually deceived him by making him feel guilt towards her when in reality she didn't like him at all, he blackens. There's r*pe as the title claims, but they eventually get together with a HEA.
