Secretary Seoha has been secretly in love with her boss, Dohyun, for a long time.
One night, the two are drawn together by their primal instincts and end up sleeping together.

When Seoha suggests pretending it never happened,
Dohyun instead remarks that he likes how “clean” it is,
and continues to create excuses to get closer to her.
Unable to refuse his proposal, she gives in.

Then one day, Seoha becomes pregnant—something neither of them wanted.
Determined to raise the child on her own,
she makes up her mind…
but Dohyun finds out the truth.
