One is a resolute business emperor, known for his ruthlessness and determination; the other is a cutting-edge CEO who appears to be equally strong, but in fact has a very special background (for example, he was once his subordinate who was a mercenary). A man encounters a commercial assassination and discovers that the personal security director is actually a loyal dog mercenary from back then. The purpose of the loyal dog's strong return this time is not only to protect, but also to completely "tether" the unruly former boss. The "former boss" simply cannot refuse this kind of protection with a sense of control.
