Chapter 90 of Jinx delivers a pivotal, emotional confrontation where Kim Dan confesses his past feelings for Joo Jaekyung in the past tense, signifying a major shift in their toxic dynamic. Jaekyung is left devastated by the realization of his actions' consequences and the damage he has caused, leading to a temporary, well-received hiatus in the series.

Thus, Chapter 90 must be the moment where the trajectory changes permanently. If Jaekyung does not change here, the story risks losing its logical conclusion. Expect Jaekyung to do something out of character: pay the bill anonymously, stay by the bedside while Dan sleeps, or punch the wall in frustration rather than hitting Dan.
