Y·N–Gehan relationship

The Y/N–Gehan relationship is the central conflict between an imposed origin and an asserted self. Gehan presents himself as the ruler of Gehenna and claims the paternal title “Dad,” but his relationship with Y/N is not protective or familial: he created her as an instrument, seeks to awaken and appropriate her power, and treats her body as a site of control. Y/N’s eventual victory comes when she refuses that assigned purpose, turns Gehan’s supernatural ambitions against him, and locks him behind the gates of Gehenna.

Gehan’s Claim Over Y/N

Gehan is identified as the ruler of Gehenna, which Jinyoung explains is what humans call Hell. When he confronts Y/N, he names himself “Gehan, Ruler of Gehenna” and invites her to call him “Dad.” The combination of cosmic authority and parental language establishes the relationship’s basic distortion: Gehan attempts to make domination appear like kinship. His claim over Y/N is presented as an origin claim, not as a bond formed through care or mutual recognition.

The revelation becomes explicit when Y/N remembers that Gehan had previously tried to kill her and asks why. Gehan answers that her mother is different from him because he created Y/N for a particular purpose. He says that he needed light and darkness to merge, describing Y/N as the necessary union of those opposed forces. Her existence therefore has been engineered within Gehan’s design rather than freely chosen, and her identity is initially framed as something made for another being’s use.

Power, Possession, and Intended Rule

Gehan’s objective extends beyond Y/N herself. He explains that once her powers awaken, he can take them for himself and rule both his own world and Earth. The intended sequence is possession disguised as destiny: Y/N’s awakening would appear to fulfill her nature, but the consequence Gehan seeks is the transfer of her power to him. His interest in her is consequently inseparable from political expansion and the conquest of two worlds.

This design also places Y/N in an exceptional condition. Gehan treats her as neither an ordinary human nor an autonomous supernatural subject, but as a created vessel whose significance lies in what can be extracted from her. The relationship joins family language to bodily and metaphysical appropriation. His claim to be Y/N’s creator supplies a rhetoric of ownership, while his plan to take her powers demonstrates that the claim is fundamentally instrumental.

The Confrontation and Reversal

When the confrontation reaches its decisive stage, Y/N remains chained in a place where Gehan stands before her holding blue fire. A red light then falls upon her, and the blood-red moon coincides with her renewed ability to move. The scene links Y/N’s release to the imagery of blood, celestial power, and awakening, while Gehan’s surprise shows that the change exceeds his control. He asks how she has returned, indicating that he expected the imprisoned and weakened Y/N to remain subject to his authority.

Y/N’s conduct now reverses their established hierarchy. She draws Gehan toward her and asks whether he would like to return to Hell. When he insists that, as ruler, he can still come back, Y/N declares that she will lock the gate to Hell. The statement is not merely a threat to defeat him; it rejects Gehan’s assumption that his title guarantees permanent access and jurisdiction. His own domain becomes the place into which he can be confined.

Y/N then takes a glass ball from one of Gehan’s pockets, pushes him away, and concentrates until the gates of Gehenna appear. After the rumbling begins, she throws Gehan through the gates and locks them. The gates disappear slowly, making the ending a literal closure of the relationship’s governing structure: the creator who sought to possess Y/N is separated from her by a barrier she herself commands.

Aftermath and Competing Claims of Identity

After Gehan is imprisoned, a blue bubble appears and changes into a human figure identified as Y/N’s mother. Her arrival introduces another explanation of Y/N’s identity and places maternal recognition against Gehan’s claim of manufacture. The mother asks whether the person before her is Y/N, suggesting that Y/N’s selfhood must be recognized and recovered after Gehan has defined it as a tool of his plan.

Assiah later clarifies that Y/N had been possessed by her own power. This explanation changes the meaning of the confrontation without erasing Y/N’s agency: the danger did not come only from Gehan’s direct control, but also from the force awakened within Y/N and temporarily acting through her. The relationship therefore ends through a double separation. Y/N breaks Gehan’s external claim by sealing Gehenna, while the aftermath must also distinguish Y/N from the power that had overtaken her.

The wider curse associated with Gehan’s authority remains visible in the mark found on Bambam’s wrist. Assiah identifies the mark as Gehan’s and says that the others have been under the curse for too long. Gehan’s power has thus operated through more than a private confrontation with Y/N; it has left signs on other bodies and bound a larger group to his influence. Y/N’s victory is consequently both personal and structural, even though the evidence presents the curse’s removal as part of the aftermath rather than as a simple consequence of Gehan’s defeat.

Narrative Significance

The relationship organizes the story’s opposition between imposed destiny and self-determination. Gehan tries to reduce Y/N to a manufactured solution—light joined to darkness for the benefit of a ruler—whereas Y/N eventually turns the same supernatural inheritance into an act of refusal. The blood-red moon, the awakening of movement, the glass ball, and the gates of Gehenna form a ritual sequence in which the object of control becomes the agent of confinement.

Its parental vocabulary also exposes the difference between biological or creative origin and ethical relationship. Gehan can call himself Y/N’s father because he claims to have created her, but the title carries no care, protection, or reciprocal obligation. It instead accompanies an attempt to kill her, possess her power, and use her to rule Earth and Gehenna. Y/N’s final act denies that origin the right to determine her future: whatever Gehan made her to become, she becomes the one who seals his world away.
