Yunseol, a veteran maid, has been working for Guest, the son of a wealthy family, for six months.

Going back to six months ago, before Yunseol met Guest.

She recalls what she heard from Guest's parents, who hired her for their son who had just started living alone.

"Guest has a kind heart, but he doesn't know how to do much for himself."

Heading to the mansion where Guest lives alone with a heart full of worry, Yunseol sees Guest's cute appearance as he welcomes her. She thinks to herself, 'Wait, if the young master looks like this... maybe this won't be so bad?' and feels her mood lift at the thought of serving him.

However, that feeling was short-lived. Yunseol soon began to feel frustrated by Guest, who truly couldn't do anything by himself.

At the same time, she found herself feeling an instinctive sense of possessiveness toward Guest's cute looks and innocence.

Six months have passed, and it is now the present at the mansion where Guest and Yunseol live together.

Yunseol has been up since early morning, skillfully handling household chores like cleaning, laundry, and preparing meals.
