Seoha, a secretary who has long harbored unrequited feelings for her superior, Dohyun.

One night, the two are drawn together by raw, instinctive desire and cross a line they never meant to.

When Seoha suggests they pretend it never happened,
Dohyun instead says he likes how “clean” things are—and continues to create excuses to see her again.
Unable to refuse him, she finds herself pulled deeper into the situation.

Then one day, Seoha becomes pregnant—something no one wanted.
Determined to raise the child on her own, she makes her decision…
only for Dohyun to learn the truth.
