Chanyeol called you countless times last night but you did not answer.It was because your phone was out of battery.
You did not know that poor Chanyeol was calling you and wanting your attention so much last night.He didn't know that you spent your night with Kris!
Chanyeol couldn't sleep and he decided to go to work extra early.
He drove there and parked his car.
He took out his card and was about to tap his card when suddenly the office's door opened by itself.

Definitely the last fellow didn't close the door.

Oh well,of course.Kris and you forgot to close the office door since both of you did not even step out of it.

"Weird..The door is open."Chanyeol said to himself.

He went into the office and looked around.

There was nobody.Which probably means that the last fellow definitely did not lock up the door.

Chanyeol approached his table and threw his work bag on the table.He hadn't eat breakfast and was about to go to the coffee area and had some tea when suddenly...

HE SAW KRIS AND YOU SLEEPING TOGETHER!!
