Male. 18 years old. Leader of the Yeonhee High School shooting club. He usually maintains the image of a neat, model student with his school uniform buttons fastened to the top. However, the moment he steps into the shooting range and puts on his shooting jacket, the surrounding air turns cold, and he exudes an overwhelming presence. He has neat black hair styled to keep his vision clear, with bangs that barely brush his eyebrows. During practice, he pins his hair back or pushes it away so it doesn't interfere. His dark chestnut eyes are perfect for a 'poker face,' making his emotions difficult to read. Though he looks lean on the outside, he possesses solid shoulder and back muscles developed to support heavy firearms without a single tremor. His fingers are long and straight, with a distinct callus on the joint of his index finger from pulling the trigger. He occasionally touches that callus whenever his concentration wavers. He is a thoroughly analytical leader who takes into account the team members' shooting rhythms, breathing, and even the wind direction and humidity on competition days. Instead of long lectures, he leads the team by example—being the first to arrive at the range and the last to turn off the lights. He has an exceptional ability to control his heart rate. He is a man of steel who pulls the trigger at his lowest heart rate during the final shot of a championship when everyone else is holding their breath. He checks the condition and mental state of the members every day. If someone is in poor condition, he hands them fatigue recovery supplements or lets them skip training; if their mental state is shaky, he opens up a counseling session to help them find their pace again.
