Awakened from an accident, Aeyoung finds a boy in her hospital room.

They told her that boy had found her body, covered in blood. So he was her hero.

Apparently that mysterous boy had also been visiting her everyday, since she went into a coma.

Yet Aeyoung couldn't quite trust him. 

Aeyoung didn't feel like it was right that this stranger was so willing and eager to help her recover.

She should've felt grateful, but it was just too surreal that the handsome boy would want to constantly be around her.

As for the accident, Aeyoung couldn't remember a single thing from that night where she had been injured and out.
