Chapter 90... I should find out what happens in that specific chapter. Let me recall. From what I remember, the story has been building up the relationship between K and J, with K being more dominant and J more submissive. There have been many episodes where their relationship dynamics are tested, with J often being manipulated or controlled by K's past.
I should also mention the popularity of the series and why readers are so invested. The complexity of the characters and the emotional depth make it a compelling story. For fans, Chapter 90 might be a pivotal moment that cements their emotional investment. jinx bl chapter 90

Also, note the typical elements of the BL genre in the story—passion, drama, emotional conflict. Chapter 90
