For Kim Hwayoung, everyday is just another day filled with nothing but sadness.
Her mother is clinging on to dear life, desperately fighting cancer.
Her father leaving his wife and daughter for a younger woman right when they needed him most.
Her life is crumbling into little pieces. She feels like she has no purpose in living anymore. Nothing can bring her happiness. She's tried things that she'd never think she'd ever do, just o keep her busy - drugs, alcohol, partying.
But then everything changes when she crosses paths with Park Chanyeol.
