Five years ago, Ling Hao, a world-class soldier king, failed to protect the beautiful scientist Su Wanqiu, allowing her to die right in front of him. Consumed by self-blame, he chose to retire and opened a tailor shop. Five years later, Su Wanqiu's younger sister, Su Wanqing, was being hunted down after witnessing an illegal transaction. Ling Hao, assuming the identity of a personal tailor, came to the Su family to act as her bodyguard. During this process, numerous beautiful women were attracted to Ling Hao and actively offered themselves to him.
