Yeah no it's crazy and disgusting I was just checking the novel to see how it ends and I scrolled and I'm like who tf is Sawol MF A DOG, HE MAKES A DOG FUCK HIM ITS FUCKING INSANE
Some people in the comments of the site said the author took it out but idk if that's true or not seeing how the Manwha already is
Apparently this is also an 'extra' after their graduation idk but here's the novel link for the people who wanna fact check and DEFEND this piece of shit Manwha
Baffled by the fact they really let A PSYCHO WRITE A PIECE OF STORY AND DISSEMINATE IT. Its like making hitler write a book with all his fcked up belief and astrocities and put a little tone of positivity in it to make the story seem digestible and publish it for the world.
Are they for fcking real?
Nah bro I sincerely doubt it I might be wrong but I believe the novel is completed...and the people who translate the novel even give a warning that this story has NO love in it ( they refered to it as a "No love trope" from what I gather the mc develops heavy Stockholm syndrome because after he escapes for the final time he gets gang raped AGAIN and now he only craves the MLs twisted abuse because it's something he's gotten used to
I even saw someone in the comments say the ML locks the mc in a room isolated and treats him like a pet even going as far as making him piss on dog pee pads
So it was officially removed from the webnovel. They did include it in the Eng fan translation, but they just put it at the end (I think it was an earlier bonus chapter before)? It definitely won’t be in the manhwa, because as mentioned (what I’m trying to assure) it was removed from the official web novel.

Yeah so uh the 'ML' makes a dog rape the mc a little later and forces him to call the dog husband
"Sawol was still thrusting into the unconscious Kwon Jiwook's hole. After a while, the dog pressed its lower body against Kwon Jiwook's buttocks, as if glued. It had swollen its glans to ejaculate inside. That wasn't coming out anytime soon. With an amused expression, Park Juyeon watched Sawol and the fainted Kwon Jiwook stuck together.
Who would've thought he'd cum from this and even pass out? Chuckling, Park Juyeon shrugged. He'd expected it to some extent. Kwon Jiwook would never be satisfied with normal sex. This incident merely turned his suspicions into certainty. Discovering an act that satisfied both himself and Kwon Jiwook filled Park Juyeon with genuine joy.
Soon after, Sawol detached from Kwon Jiwook as if nothing had happened. Wagging its tail, it seemed quite pleased. Park Juyeon grabbed Sawol's face, with its characteristic gentle Labrador smile, and stroked it with both hands. Good job, Sawol. He said, planting multiple kisses-pop, pop-on its face. It was pure, uncalculated affection." - chapter 40 of the novel
