Her father died when she was a child, then her mother ran away to marry another man. Eun-nim and Choi Joon-young grew up together; Eun-nim's grandmother had taken in Joon-young and his mother after seeing her suffer at the hands of her husband. Though they treat each other as siblings, Joon-young slowly begins to see Eun-nim as a woman. Eun-nim is cheery and energetic outside, but deep in her heart, her longing for her mother and loneliness grow stronger as time goes by. By chance, Eun-nim gets hired as an intern at an organic food company, Green Love. There, Eun-nim meets Lee Se-in, the third generation offspring of a conglomerate. As the heir of the business, Se-in studied in America and has looks, brains, and wealth; he is also selfish, spoiled and immature. Meanwhile, Hong Joo-mi is also the picture of perfection; proud, confident, beautiful, and unused to failure, Joo-mi went to the best schools and is now the youngest team leader at Chairman Lee's company. At first, Eun-mi and Se-in quarrel everyday over nothing and everything, but in the end, they fall in love with each other. But one day, her mother appears after all these years and asks Eun-nim to donate her bone marrow, to save the life of her son...
