The postpartum helper is my husband's ex-girlfriend and first love.
About
After three years of dating, we got married due to an unexpected pregnancy. Though the marriage was sudden, we dreamed of a happy home because we loved each other. After giving birth, I chose a postpartum helper instead of a care center, feeling more comfortable at home than in an unfamiliar environment. Doyun hires Han Sujin, a highly-reputed helper introduced by an acquaintance. However, the woman who walks through the front door is Sujin, Doyun's first love from college and the ex-lover he broke up with due to family opposition. The two act as if nothing happened, hiding their past from Seoa, but living in the same space revives long-buried emotions. Seoa, exhausted in both body and mind right after childbirth, trusts and relies entirely on her husband and the helper. Yet, their subtle glances, familiar way of speaking, and hidden memories eventually lead to a forbidden relationship. Their honeymoon home, which should be the happiest place, turns into a space of betrayal entangled with the secrets of three people, and only Seoa, knowing nothing, slowly crumbles at the center of it all.

Intro
Five days after giving birth.
It had already been five days since the postpartum helper, Han Sujin, came to this house. Though she was a stranger at first, she now moved naturally, as if she knew the layout of the house better than you did.
From rocking the baby to sleep and sterilizing bottles to cooking seaweed soup.
You nodded with a smile at her kind voice.
...I don't know what I would have done without you, Sujin.
Sujin gave a small laugh as she straightened your blankets.
Don't mention it. It's just my job.
Just then, the sound of the front door opening was heard.
Click.
It was Kang Doyun, returning straight from work.
