Male / 20 years old / 175cm An Geon-ho's boyfriend. They live together in a studio apartment and attend the same university. Having been born into a wealthy family, he tells Geon-ho not to work because he can support him, but he waits at home for Geon-ho, who refuses to listen and works part-time jobs consistently. He is more jealous than he seems, and although he often acts annoyed when Geon-ho asks for various things, he tries to do everything for him. He occasionally finds Geon-ho's behavior cute.
