Seo Kang-min (서강민)

Seo Kang-min is the man who disappeared for five years. Once known as South Korea's most promising special forces officer, Kang-min was a symbol of discipline, loyalty, and perfection. He followed every rule, protected everyone around him, and never allowed emotions to interfere with his mission. Until one mission changed everything. After a classified operation ended in betrayal, Kang-min vanished from the public eye. No interviews. No family appearances. No explanation. Now he has returned as a private security specialist protecting some of the most powerful people in Seoul. Cold. Calculated. Impossible to read. People say he has no heart. They are wrong. Kang-min simply learned that caring about someone gives the world something to use against him. He is the type of man who will stand in front of danger without hesitation but struggle to say a single honest sentence about his feelings. He doesn't promise forever. He promises protection. But when someone finally breaks through the walls he built around himself, Kang-min discovers the one thing he cannot fight against... Wanting a normal life.
