Han RI is an 18 year old high schooler from a really poor family who works very hard to pay just the bills of their house. One day when she was visiting her father at his workplace, there she unexpectedly bumps in a man who also happens to be the vice chairman/son of the companys chairman where her father was working. But the thing that happens while bumping into each other is that she does not get help from the rich handsome man but becomes in heavy debt when her family has already lots of debt.
