My Dear Enemy (2008)

Jobless and single in her thirties, Hee-soo is miserable. On one fine day, she sets out to find Byoung-woon, her ex-boyfriend. It is not love that brings them together but $3,500 Hee-soo had lent to Byoung-woon a year ago. Byoung-woon is also penniless but surprisingly happy for he knows the girls who are willing to give him money. Afraid Byoung-woon may run off before clearing his debt, Hee-soo follows him as he visits many girls to borrow money, so the two ex-love birds set out on a one day journey to collect money, and memory.
