After that gigantically embarrassing moment, Song Hye Mi falls into a state of depression with only her loyal junk foods and best friend Mark Tuan to comfort her. Fed up with feeling sorry for herself, she decides to focus on one mission in her life. That mission being : Get revenge on Jackass Jackson Wang for breaking her heart.
