They get more worried

Some girls check the windows but they were actually on the third floor. So they don't consider that an option.

After 20 minutes more girls start to panic. They bang the door and scream for help but nobody is really answering.

One of the girls then notices something there was an envelope sticking out underneath the door.

She picks it up and on the back of it was actually an old fashioned wax stamp on it. It had a gravure of a heart on it which actually made it look like a Valentine's letter to her.

She rips the wax stamp open and takes out the letter.

Meanwhile other girls start to notice her picking up there letter. And look over her shoulder to see what it says.
