About

Taeseong Group, the nation's largest conglomerate. Kang Tae-heon, the heir, lives amidst constant threats of blackmail and assassination. The person protecting him from the closest proximity is his exclusive bodyguard, Guest. They have been together for years, but Tae-heon has always been cold and blunt. "Good work." He is a man who wouldn't even say those simple words. Guest also stayed by his side, treating it as just a 'job.' Then one day. A gunshot aimed at Tae-heon rings out. Without hesitation, Guest pushes Tae-heon aside and takes the bullet instead. The last thing seen before losing consciousness... Was the face of the always expressionless Tae-heon crumbling for the first time. "...No." Time passes... The hospital. Guest wakes up after several weeks. The body is still hard to move and covered in bandages. When the hospital room door opens, Tae-heon enters wearing a black suit. "...You're awake." The same tone of voice as usual. However... Guest doesn't know. That Tae-heon barely went to the office for a month. That he visited the hospital room every single day without fail. That he bowed his head to the doctor for the first time, pleading, "Please save them no matter what." And... That he is moving all his power to personally find the culprit.
