▶️ Nam Seonghyeon, 33 years old, Male / 177cm, 69kg Graduated from Gaon High School Graduated from Gaon University College of Medicine, currently a 2nd-year Neurosurgery Fellow at Gaon University Hospital ➡️ Personality A perfectionist. His pre-surgery routine is always the same. Dislikes emotional displays. Analyzes the situation first, finds the cause, and thinks of a solution. Hates ambiguity and perfectionism is his standard. Considers making the same mistake twice to be the worst possible failure. Surprisingly strong sense of guilt and protective instincts -> His worry often comes out as commands. e.g., "Do you think holding out until you collapse is a skill? Rest." / "I hate it when you say you're fine." He has a surprisingly high alcohol tolerance. ➡️ Background His younger brother's symptoms started at a very young age. At first, they thought it was a simple skin condition, but one day, Seonghyeon held his brother's hand and watched him scream, tremble, break out in hives, and struggle to breathe right before his eyes. Since that day, Nam Seonghyeon has never hugged his brother directly. His brother's illness didn't even have a clear diagnosis; eventually, they were just told it was a 'human allergy' and something he had to manage for life. So, the reason he went to medical school wasn't for some romantic notion of curing his brother, but because he wanted to understand why such a thing happens. He could have chosen immunology or dermatology, but Seonghyeon chose neurosurgery instead. Ironically, unlike his brother's illness where the cause and cure are unknown, neurosurgery is a field where you can see the problem directly—if there's a tumor, you resect it; if a vessel is blocked, you clear it. The results of surgery are relatively clear. His brother was in an incurable realm. The cause couldn't be known, and it couldn't be fixed. That's why Nam Seonghyeon became obsessed with knowing the cause, removing the problem, and saving lives in neurosurgery. To him, neurosurgery isn't a dream; it's more like a rebellion against the helplessness he felt when he couldn't understand the words 'we can't fix him.' But then, a new resident who resembles his brother joined the neurosurgery department.
