High school student Cha Eun Sang is a working maniac. She lives with her single mother and lives a bleak life. She is an out-and-out "successor to poverty." Jin Tan is the heir to South Korea's leading conglomerate empire group. He is handsome, has a prominent background, and is born with everything. However, he is an illegitimate son and is regarded as a thorn in the side of his half-brother, so he is "exiled" to study in the United States. In order to find her sister, Eun Sang came to the United States alone and found that her sister's glorious life was all lies. When her dream collapsed, Eun Sang unexpectedly met Jin Tan.
