Sulli has been living for her career. She doesn't care about her lovelife...all she thinks about is journalism...she can't be blamed, she learned not to give in to love the hard way back in highschool. But just as she comes back to Korea to continue her career and be with her family...A shadow of the past threatens to make everything in her life chaotic again... How will she handle it when the boy who broke her heart in highschool...is actually her officemate?
