### Summary
The latest chapter delves into the disturbing origins of the time-traveling antagonist, Sejoon, through a powerful flashback that has horrified the readership. The narrative reveals that Sejoon’s fixation began in junior school when he, a socially awkward student, dangerously misinterpreted basic kindness from Mirim as romantic interest. After she remembered his name, he developed an infatuation that, upon her gentle rejection, twisted into a psycho-entitled obsession. This backstory has elicited a visceral reaction of disgust and anger from readers, who overwhelmingly condemn Sejoon as a "creep" and a "sick bastard." The scenario is described as terrifyingly realistic, with many female readers sharing their own experiences of men reacting with rage to rejection, thus framing Sejoon’s villainy as a chillingly familiar form of toxic entitlement. This revelation provides the clear motive for his future actions, cementing him as the premeditated murderer the protagonists must stop. The chapter concludes on a tense cliffhanger, leaving readers to speculate on the full timeline of his stalking and the methods he might be using in the present.
