After Hae-jun and Jae-hoon begin dating, they celebrate their first Christmas together. Under Jae-hoon’s carefully planned surprise, the two arrive at a private seaside villa. There, Jae-hoon presents Hae-jun with an anklet—an intimate symbol of devotion and control—asking him to always remain within his sight.

An uninvited visitor, Kang Su-hyeok, suddenly appears and reveals Jae-hoon’s possessive control and the childhood trauma Jae-hoon refuses to confront to Hae-jun. With a third party stepping into their world, will the relationship between Ha-jun and Jae-hoon begin to change?

Ha-jun meets Su-hyeok at a bar, hoping to learn more about Jae-hoon’s past. But when Jae-hoon discovers Ha-jun went out behind his back, his possessiveness spirals out of control. What was once a sweet relationship quickly begins to fall apart.

Jae-hoon once again warns Ha-jun not to wander off on his own and to obey him alone. With Ha-jun staying by his side, Jae-hoon slowly opens up about the domestic violence and separation he endured as a child—revealing the fear at the heart of his need for control and possession.

Min-woo tells Jae-hoon that he has understood his preferences since childhood, and that he was even willing to become the kind of person Jae-hoon likes. It is also the first time he has seen Jae-hoon maintain such a long-lasting relationship with someone under contract.
