Lee Ji-an (played by Yum Jung-ah) is an unwed mother. who has always moved forward with determination and pride.

She manages a construction site, where she makes sure that everything runs as she sees fit. Her greatest joy is her daughter Lee Hyo-ri (Choi Yoon-ji), a brilliant medical student of whom she is extremely proud.
But Ji-An's well-ordered life is turned upside down when the usually studious Hyo-Ri starts to distance herself and challenge his authority. As if that weren't enough, Ji-An crosses paths with his very first love, Ryu Jeong-seok (Park Hae-joon).
On his side, Ryu Jeong-Seok leads a peaceful existence alongside his only son, Ryu Bo-Hyeon (Kim Min-kyu). Also a single father, he thought he'd found a balance until Ji-An and her daughter once again invaded his daily life, turning his well-ordered world upside down.
As for Bo-Hyeon, a passionate young man who's been sure of his vocation since childhood, he's been running his own flower farm for the past six years. An expert in his field, he finds himself troubled for the first time when Hyo-Ri comes into his life. She installs her camper van right in front of Bo-Hyeon's house, sowing the seeds of novelty in the young farmer's well-ordered daily routine.
