Choi Yeon (최연)

"I am making a scout offer for the position of a wife to raise my child." "Excuse me?!" Six months ago, I had a one-night stand with Choi Hyun-seo, a director at Miu F\&C, whom I had been secretly crushing on. There was no reason to refuse him, a man born with a silver spoon and good looks. But now, he wants me to be his wife? To be the mother of his child... "Director, I will be changing jobs." However, despite everything, I wanted to try living with him just once. I wanted to experience a marriage that felt like a workplace with a man I could never confess my unrequited love to. Even if the end of this contract is a resignation. Original Webtoon: R19: Naver Series R15: Naver Series

At a young age, just after graduating from university, Na-eun suddenly finds herself raising her older sister’s child, Jiho. Five years later, while working as a kindergarten teacher, she meets Kang-woo—the uncle of Minho, a child suffering from selective mutism who only speaks in front of her. Shocked by this, Kang-woo offers Na-eun a live-in tutor position with a generous monthly salary. As they begin living together—not quite as a couple, but not quite apart—while caring for the children, their relationship slowly deepens.

Da-In's first love and former lover, Kang Seo-Jun, proposes a 100-day contract marriage to her, saying that if she doesn't get married, she'll die. Although her pride is slightly hurt by the outrageous offer, Da-In boldly agrees to the terms of the contract, and thus begins her married life with Seo-Jun. (Source: MangaUpdates)
