I’ve got no idea cause I haven’t read the novel but this is based on what someone commented
SPOILER BELOW
Park ask Jiwook if he’s hungry. Jiwook is confused because Park is laughing. He then presents him a dog bowl filled with dog food. Park finds it amusing while Jiwook freezes. Park then puts Jiwook on his lap and said it was a joke. In the mist of Park thinking, he recalled a time where he had placed several pads in the corner of the room and ordered Kwon Jiwook to defecate there. Despite begging desperately, Kwon Jiwook couldn't hold it in and ended up defecating on the pad.

Is the manhwa really accurate to the novel? If that’s the case doesn’t that mean they will be showing the dog shitting part also what is the ending
