Several characters make sexual comments, take unauthorized photos of girls (including minors), stalk people, and make implied touches or threats. It appears throughout the entire story, especially with antagonists who act as harassers or predators. There are mentions of rape or sexual assault (even if passing or implicit) because it is discussed in casual dialogues, flashbacks, and in the villains' backstories. Examples: the past of some antagonists is mentioned, or traumatic events are alluded to. There is sexual relation/assault between an adult and a teenager because an adult instructor attempts to sexually abuse high school students (teenage girls). The adult is Heemin Kim (alias Zeus), a camp instructor. In the Autumn Boot Camp Arc (chapters 42–45, peak in chapter/episode 45), Heemin Kim (Zeus) attempts to rape Mira Kim in an isolated storage room: he punches her in the face (blood shown), orders her to strip, starts undressing her himself, and partially pulls down her pants. No penetration or completed rape occurs. Zack Lee and instructor Won Bin arrive in time, stop him, beat him, and pull him away. Zeus is arrested and later imprisoned for attempted rape. Jiho Park's implied rape/gangrape (Juvenile Prison Arc, chapters ~180–187, with references up to ~200+) He enters juvenile prison and is harassed/bullied by Darius Hong and others. Sexual assault (implied rape/gangrape, especially by Darius) is heavily suggested through scenes, dialogue, and his breakdown. He suffers extreme psychological trauma: mental collapse, flashbacks, self-harm, drastic personality shift, and loss of sanity (including solitary confinement). PTJ later confirmed the assault in a blog post, though it was heavily implied/censored in the comic.
