After that accident, Haera and her family went to the States to get medication for her. A week after her left, Daehyun broke up with his girlfriend. He was so sad and kept blaming himself for that accident. He caused Haera, his best friend since long time ago to feel so much pain. He really regret it. It will never happen if he did not date that devil, Yoora. But who knows it will ended up like this? He was too blind to realize it before, right?

What’s going to happen next? Will he and Haera meet each other again? Is there something they hide from their friends?
