Injured

What if chanyeol from exo was injured and has to be hospitalised for a week!
And what if his bestfriend would know about this.
What will happen if he finds out that she has a secret.
His bestfriend did everything to him smile. And to make him feel better.
But what if one day somerthing happened to his bestfriend that he didn't want to happen.

Caution: this is a sad story
