Love Guide for Dumpees (2015)

They’ll meet 10 times, and then never see each other again–that was the deal. What started as a sexually-fueled fling becomes much more when two dumpees decide to use each other to get over their exes. Jeong Hun meets Shi Hoo at his ex-girlfriend's wedding. Both were dumped in relationships. After they drink together, they end up sleeping together. To get over their exes, they agree to meet nine more times.
