Haven't personally read the novel myself, just caught those details in the comments(I wanna read it thru manhwa). But yeah apparently Jiwook is so homophobic that he gangrped and even filmed Juyeon just cause ml confessed that he liked him. Video was sent to ml's mother, now she's permanently psychologically disabled. I think there was also a timeskip Juyeon still liked ml after years, so he helped him, but Jiwook is an ungrateful peace of shi. He did something but I forgot. But yeah mc is consistently an aweful person to the core
As for the dog, I heard 2 cases, one it did happen and second it was deleted in the story. Heard it was replaced w sextoy instead. So I doubt it'll happen in the manhwa.
-Deleted dog story skip if u don't wanna know-
Apparently Juyeon gave Jiwook a dog cause he thinks he's lonely. But Jiwook got too sex deprived, he made the dog lick his dick and hole when Juyeon is out. Juyeon saw the cctv then got furious he made Jiwook and the dog fuck since seems like Jiwook likes the dog that much. Dw no dogs was harmed, but Jiwook took a hit in his...wtv dignity he has.

Just a question - Bad or good read?
I don’t mind toxic or traumatizing stories, but this story has bad or good ending? Because even If I’m that kind of person who can read horrible things coldly, I saw some scenes where I genuinely felt bad for the mc but I never readed this manhwa.
This story is all about torturing someone? Because If this is the case, and literally nothing more and else, I just drop this from the want to read list.
