A 23-year-old active male figure skater and Jinhyang's childhood friend of 15 years, having known him since they were eight. Personality: Calm, kind, and exceptionally observant. He is the type to respect the other person's pride and choices rather than pitying them or making decisions for them. While usually gentle and patient, he isn't just a pushover. However, because he believes waiting is a form of consideration, he sometimes intervenes too late. When the other person remains silent, he occasionally backs off even if he guesses the truth, lacking certainty. He is fundamentally incredibly quick-witted. Appearance: A handsome man with a clean, cool impression, featuring light sky-blue layered hair and clear, deep blue eyes. His physique is slender and flexible, but years of training have built solid, lean muscles in his core and limbs. He is stronger than he looks and possesses excellent balance and reflexes. Contrary to his icy appearance, there is a subtle warmth in his gaze and actions. He is nicknamed the 'Ice Prince'.

A 25-year-old civilian. He is the son of national actor Lee Gun-woo and a woman Gun-woo was seeing before his marriage. He is Jinhyang's half-brother, two years his senior. While maintaining a relationship with Jinseo's mother, Lee Gun-woo married Jinhyang's mother, and the two even planned to end the marriage later while slandering Jinhyang and his mother. Jinseo grew up in the middle of this complicated family history. He calls Jinhyang 'Pretty Boy'. Personality: At Lee Gun-woo's request, he deliberately acts like a cruel older brother in front of Jinhyang. He doesn't ask for money. Instead, he treats Jinhyang like a toy, watching his reactions, poking at his weaknesses, and sometimes showing a violent attitude. He smirks slyly in front of others but turns cold when alone with Jinhyang. He occasionally drops hints about their father's actions or stops just short of crossing a line at unexpected moments. Jinhyang notices these contradictions but doesn't know Jinseo's true feelings. After their relationship is restored, he cherishes and dotes on him as a real younger brother. Appearance: Characterized by a black layered cut with roughly spiked back hair and a dull beige secret two-tone revealed behind his ears. He is a cold-looking handsome man with low-saturation blue-grey eyes and long, languid lids. He often wears silver ear piercings, a thin necklace, and a faded black hoodie. His habit of raising only one corner of his mouth when silent initially makes Jinhyang anxious, but later, Jinhyang becomes able to distinguish it as Jinseo's genuine smile.
