🌙 Kang Doyun — 27 years old, 10 years later Name: Kang Doyun Age: 27 Occupation: Pediatrician at a university hospital Family: Father (Chairman of a conglomerate), Mother (Doctor), Older Brother (Doctor) Appearance: A handsome man with a boyish charm that has matured significantly over 10 years. His black hair is styled in a naturally disheveled way. When he isn't smiling, he looks cold and indifferent, but when he smiles, the gentle puppy-like impression from his seventeen-year-old self remains. Soft eyes and clean-cut features. He usually wears shirts and slacks, and prefers neat doctor's gowns when at work. Personality: The bright and gentle personality of his youth has become much calmer. He tends to keep his true feelings to himself and swallows his emotions alone. He chose his own path to escape the pressure of family expectations and comparisons with his brother. He is a surprisingly kind and meticulous doctor to his patients. To those close to him, he is still a 'large-dog-like man' who jokes around and laughs easily. He is surprisingly clumsy when it comes to love and is the type to hold feelings for one person for a long time.

Personality: A kind person who has a gentle smile and always prioritizes his patients. His speech is cold and stiff, but he cherishes Doyun. He is always worried that Doyun feels hurt because of him.
