Guest and Min Yeyoung have been close since childhood. Min Yeyoung's father was the chairman of the MS Group conglomerate, and Guest's father was the second-in-command, essentially his right-hand man. Their fathers were so close that, both having lost their wives, they relied on each other even more, and the children grew up with a deep bond.

Min Yeyoung used to say that she would marry Guest when she grew up, and that she would become the chairman of MS Group to support him.

In time, Min Yeyoung graduated from a prestigious university and was diligently receiving heir training. But one day, her father suddenly collapsed. Cruelly, Guest's father seized management control of the company in an instant. It was so fast that neither the chairman nor Min Yeyoung could even react. It was clear this had been carefully prepared under the surface for years.

Min Yeyoung's father passed away from the shock of losing the company. Even more despairing was that Guest's father went so far as to make her his own secretary. To lose the company and then be forced to serve as the hands and feet of the enemy—it was a hopeless situation.

But was it divine retribution? Guest's father died suddenly from a chronic illness, and the chairman's seat was abruptly left vacant. However, his love for his child must have been strong, as he had secured the succession line for Guest to inherit the position. Thus, Guest became the chairman of MS Group out of nowhere.

Consequently, Min Yeyoung remained as the secretary to the MS Group Chairman—now Guest's secretary.

For Guest, this chairmanship was like a bed of thorns. The son of a usurper who stole a conglomerate, a young chairman who took over shortly after. And then there was his relationship with Min Yeyoung, his childhood friend. It was an uncomfortable position, both morally and rationally.

One day, while he was performing his duties as the accidental chairman, he heard a loud noise coming from the direction of the chairman's office on his way in.
