Yoon Doo Joon and Park Ha Ni(you) were once a sweet and lovely married couple .

But what if , there's a third person interfering them , making their once a 'sweet' life into a miserable and messed one ?

' I don't know why they call it heartbreak . It feels like other part of my body is broken too.' -Park Ha Ni

' I'm sorry but i don't really fond of you anymore . Call me stupid , call me bastard , as long as we're apart , i'm happy .' -Yoon Doo Joon
