For a comic about a stalker and a serial killer, this is a given.
- Chapter 1/2/3, Bum encounters the poor screaming woman bound up, gagged, and noticeably beaten in Sangwoo's basement. As he tries to save her, Sangwoo suddenly creeps behind him... and proceeds to break Bum's leg by pushing him down the stairs and injure him badly. In the next scene, Bum wakes up chained to the wall and face to face with the woman's corpse. Sangwoo mocks the woman and proceeds to breaks Bum's other leg with a hammer when he noticed that it was still working, with Bum pleading for him to not do that. Sangwoo intents to torture Bum, but noticed that Bum pissed himself while crying. When he brought him up, he threatens him to never cross the line or else he'll slash his throat, describing the process.
- Chapter 7, Sangwoo (pretends) to go out and after he "left", Bum, with still broken legs, saw his chance of escaping. As he uses the chair to get to the drying machine to get his clothes changed, he pulls in shock dismembered corpses from a drying machine out (although it was a hallucination and it was actually the clothes of the women Sangwoo has killed). Due to how Sangwoo mutilated the body of Bum's uncle later on, it is however to be assumed that he still did that to his victims. Bum, with changed clothes, crawls to the front door and remembers the moment when Sangwoo threatened to slash his throat if he dares cross the line/to escape. As Bum had his hand on the door handle and was about to open it, he asks himself if he really wants to back "there" (Having to live with his abusive uncle). Suddenly, a hallucination of Sangwoo appears who reminds him that he already crossed the line and that his Uncle's waiting for Bum. Bum lets go of the door handle and remembers the sexual abuse of his uncle, with tears falling down. Time passes and Bum doesnt know what to do, remembering how he loved Sangwoo before he found out how he actually was. The hallucination of Sangwoo pets Bum's head and Bum while crying, tells "Sangwoo" that he loves him. "Sangwoo" goes psycho with a Slasher Smile and tells him repeatedly that he chose this, with Bum in shock. Bum notices that the time passed again and as he looks back to the kitchen, he sees a hallucination of Sangwoo killing him. Bum freaks out as the clock kept ticking, with Sangwoo approaching him with the knife and about to stab him, doing another Slasher Smile. Bum looks up and realizes that Sangwoo's still not there and that he's gonna go crazy if he's gonna stay there any longer. As Bum thought that he should just go already, he remembers his uncle again, and even then, that that would be better than dying because of Sangwoo. As he opens the door, noticing the smell of the rain and seeing the sunset after such a long time again, he also notices the faint smell of cigarette smoke. In shock, he realizes that Sangwoo never really left and was waiting in front of the door the whole time.
- Chapter 10, where after Bum loses in a card game against Hyunwoo, Hyunwoo is forced to kill him. However, Hyunwoo is too afraid to kill Bum so Sangwoo blindfolds him and decides to push a tied up Bum to the knife he's holding, while Bum is screaming in terror the whole time. Hyunwoo is instead tricked into stabbing himself, and dies instead. Sangwoo then describes how nicely warm blood is as he rubs the man's blood into Bum's face. Bum is (even more) traumatized.
- Chapter 19, it ends with Bum having a blackout moment after all the abuse he went through because of Sangwoo and having a triggered PTSD Moment, killing Jieun by stabbing her multiple times while screaming "DIE" as Sangwoo watches, smiling. To top it all off, we are then treated to a full view of Jieun's bloody corpse and Bum analyzing the damage in rather excruciating detail. Not helped at all by his smile and statement that he "feels nothing". Sangwoo seemed shocked, but then disappointed, because he thought that Bum might enjoy it like Sangwoo does, but Bum didn't and was dissociating the whole time.
- Chapter 25/26, Bum wakes up from a dream with no pants on, someone grabbing his waist and making noises behind him, revealing that it's his Uncle raping him. A traumatized Bum blames himself the next day and runs away from home after accidentally self harming with a knife. Before the uncle went searching for him, Bum came back and knocked at the door. The uncle quickly grabbed a wodden bat and told his mother to open the door, wanting to punish Bum. Bum, still traumatized, apologized for running away. While Bum went back to his room, they noticed his hand bleeding. The uncle pounded against the door, telling Bum to open up while Bum cries. The next day, Bum's Grandma told him that his uncle wouldn't come home that night, facilitating Bum. Before they went to sleep, she told Bum that he should sleep in his Uncle's room since he wouldn't be home at that night anyways. However, it turned out to be a lie since he came home and ended up beating him in his room while he's naked with a cane then fully rapes him violently and disturbingly.
- Chapter 29.5, Bum's whole nightmare, from him being alone in a place he's never been before, to the creepy guy with no eyes and cut fingers who resembles his uncle, to the disturbing picture of Min Jieun, to the Music playing, to the cinema where bad memories of Bum's past are playing, including him being raped by the Uncle, as the people in the cinema laugh, as Bum freaks out and wants it to stop playing, as suddenly a cut appears on the wrist, as the people suddenly all look to Bum, who suffers from severe anxiety, to the movie ending and suddenly a clown appearing and chasing Bum, to the creepy picture of Sangwoo's mom appearing, to Bum finding himself in a corner with no escape and breaking down as the Clown approaches him, it's BY FAR the worst nightmare fuel moment in the series.
- Chapter 49, Bum is having a dream which turns into a nightmare when his Uncle appeared and is about to kill him and the nightmare only got worse until Bum woke up.
- Chapter 63/64/65, From Sangwoo's severe abuse to Bum, to Seungbae almost dying, to Sangwoo's Psycho face and almost killing Bum who severely pleads for his life.
