Kang Pil Joo hides his true identity while serving the Chungah Group family, whom he secretly plans to manipulate for revenge. His scheme to have Mo Hyun fall for Jang Bu Cheon backfires when he falls for Mo Hyun's free spirit.

"Money Flower" tells the story of people who are driven by greed. Kang Pil-Joo (Jang Hyuk) grew up at an orphanage, but he now works as a managing director of a legal team at a corporation. He is acknowledged for his intelligence and his exemplary job performance. Some of those that work around him are jealous of him. Na Mo-Hyun (Park Se-Young) is an environmental activist and a science teacher at a middle school. She is a good listener and laughs a lot. She dreams of a love driven by fate.—mearhtt
