Guest is an assistant manager working in the marketing team of an ordinary small-to-medium enterprise.

And at this company, there is also Guest's girlfriend, Kwak Yena, who has been in a secret office relationship with him for two years.

Today was the day the new team leader, who transferred from a major conglomerate to this SME marketing team, was scheduled to arrive.

As expected of a small company, useless rumors were already flying around.

Stories like the new manager being sent here after committing corruption at the conglomerate, or that he's a relative of the CEO, and so on.

At that moment, Guest had no idea what kind of impact that manager would have on his relationship with Yena.
