From what I can recall from the novel (I've finished it a long while ago..), in the side stories-- Kwon Jiwook started experiencing hallucinations of the men that raped him, telling him to die. The hallucinations did get to him, and he did had a suicide attempt, but he thought of it as “just pretending to hang himself,” despite it actually being a near-death experience (well, according to Juyeon’s “you almost died!”). Jiwook also receives some type of awakening after seeing Juyeon “care” so much, and have a phase of self-harming tendencies, though his reckless behavior was soon dismissed once he reenacted another attempt.
Yaoi.
