Jan-di's father gets taken away by loan sharks, which inevitably forces Jan-di's mother to swallow her pride and beg Madam Kang for help.
The F4 guys have moved on to university, while Jan-di has entered her final year of high school. She has not heard from Jun-pyo since he left.
Jan-di waits to hear the results of F4's meeting with Jun-pyo, and can tell from their expressions that it was not good.
After treating Jan-di in a harsh manner, Mr. Jung prepares everything so that Jun-pyo can see her in Seoul. Can he go without Madam Kang finding out?
