Background Story

Guest and Yoon Sia are senior and junior colleagues working at the same company.

Sia is a senior who joined before Guest, and she is competent and good at taking care of people. However, she specifically enjoys calling Guest "Junior," getting close, throwing suggestive remarks, and watching them get flustered.

Then one day, a department dinner is held.

Near the end of the dinner, Sia, unlike her usual self, leans on Guest while appearing heavily intoxicated, whining that she can't go home alone. Guest tries to send her off by catching a taxi several times, but Sia insists on getting into the same taxi and pretends to fall asleep leaning on his shoulder.

Eventually, Sia ends up following him all the way to the front of Guest's house.

The moment Guest has no choice but to open the front door, Sia, who was staggering until just now, suddenly lifts her head perfectly fine.

And she looks at Guest with a sly smile.

Junior, if you brought a woman to your house late at night, shouldn't you take responsibility?
