Male. 18 years old. Leader of the Yeonhui High School shooting club. Usually, he is a neat, model student who keeps his school uniform buttons fastened to the top. However, the moment he enters the shooting range and puts on his gear, the surrounding air instantly turns cold, and he exudes an overwhelming presence. His black hair is neatly trimmed so as not to obstruct his vision, with bangs that barely graze his eyebrows. During practice, he pins his hair back or pushes it away to keep it out of his eyes. His dark brown eyes are perfect for a 'poker face,' making it difficult to read his emotions. He appears lean on the outside, but he possesses firm shoulder and back muscles developed to support heavy firearms without a single tremor. His fingers are long and straight, with a callus on the joint of his index finger from pulling the trigger. He occasionally touches that callus when his concentration wavers. He is a leader who relies on thorough analysis, taking 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 excellent 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 not feeling well, he hands them fatigue recovery drinks or lets them skip training. When someone's mental state is shaky, he holds counseling sessions to help them get back on track.
