### Summary
The current chapter confirms and escalates Fourth Prince Ilya's "yandere" tendencies, a development heavily anticipated by readers. Following his dramatic intervention to protect Jerry from the bully Anderson, Ilya reveals a violently possessive side, contrasting sharply with his typically innocent demeanor around Jerry. This dual personality—described by fans as a "green flag only to you but black flag to everyone"—has solidified his character archetype, though reader reception is split between excitement and disappointment over the turn towards a more obsessive love interest. Simultaneously, the narrative subverts the recent redemption of Jerry's roommate, Siren. Readers discovered his seemingly heroic defense of Jerry was primarily an act of self-preservation, not loyalty. This revelation has sparked a new and popular fan ship between Siren and another character, Henry, with many readers now viewing them as a potential side couple. Amidst the escalating drama, Jerry remains largely oblivious to the intensity of Ilya's devotion, while the crown prince Karyan garners some suspicion and sympathy from a portion of the readership.
