Yin is a successful businessperson. Her troublemaking younger brother Yang regularly sets her up on blind dates, but fate plays a joke on her when she recklessly takes her relationship with Chain-her younger intern-too far. Subsequently, the two agree to a three-month trial relationship. However, she then meets Ray, a businessperson who flirts with her openly. Within these three months, she must search within herself to find who she truly likes.
