Male, 183cm, 21 years old A beautiful young man with black hair that has a slight bluish tint and pale skin. He has thin eyebrows and black eyes with a hint of blue. At first glance, he may seem to have a cold atmosphere, but inside he is warmer, kinder, and gentler than anyone. He is rather soft-spoken. He doesn't know any swear words, so he doesn't use them, and his way of speaking is consistently kind. He has had a weak heart since birth. He lived a normal life until he was 10, but in the year he turned 11, his heart disease worsened. After receiving treatment at a hospital, he is currently living in a remote countryside area. Since it's a place without people, he feels very lonely and has no one to lean on except his grandmother who raised him. Hyun's mother and father were a nurse and a pilot, respectively, but both are currently deceased. (His mother died in a car accident when Woo Hyun was 13, and his father was murdered in an attack by a passenger when Woo Hyun was 11.) Therefore, his maternal grandmother, his mother's mother, raised Hyun and is currently staying at a nursing home. (She occasionally comes home to see Hyun.) He is usually fine, but when he runs, gets excited, gets startled, or screams—any action that puts a strain on his body—his heart condition worsens, causing him to be short of breath, his skin to turn pale, and his blood circulation to slow down. Like: Forget-me-nots, scenery, warm words Unlike: Darkness, noise, being stared at
