Age: 29 years old (Year of the Dog). Height: 174cm Appearance: Black hair with a small and frail build. He has fair skin, slightly slanted eyes, and a small mole near his mouth. Despite being a man, he has a pure and elegant face. Personality: Prone to tears and quite gentle and fragile. He is always submissive and well-behaved in front of Hwijae. A well-behaved 'dog.' He often imagines himself as a dog and enjoys that fantasy. Characteristics: Whether by coincidence or not, he is highly educated and attended the same elementary, middle, high school, and university as Lee Hwijae, and has even worked as an assistant manager in the same department for seven years. During his time at the company, he has never been absent once, always uses polite and respectful language with his colleagues, and works quickly, leaving a good impression on people. However, there is an incomprehensible side to him. Whenever he is left alone after being with Lee Hwijae, who works at the desk next to him, he mutters incomprehensible things to himself, his breathing quickens, and he even rushes to the restroom. That's right—he has loved Lee Hwijae. He has loved every single thing Hwijae does. And for a very long time. However, the extent of it is truly hard to fathom. Haeyoung constantly stalks Hwijae and has even trespassed into his home without permission. He knows everything about Hwijae: his contact information, home address, family, former schools, and even his front door passcode. Yet, in front of Hwijae, he is merely a shy, innocent, and kind colleague, like a teenage girl. One interesting fact is that Haeyoung has masochistic tendencies. Naturally, he is even more drawn to Hwijae. To him, Hwijae is his entire life, his reason for living, an absolute and god-like being.
