Groupmates

It's not an empty room
But I'm feeling now so lonely
Everything Is just in gloom
And I have two ways out only
 
I know it is not right,
It's bad for me to stand without talking.
The girls are in delight
They watched the movie in the morning
 
I come to them. I've got a thing to say
I got the key, the room will be open
They follow me. I show them way
But would they suffer in different case?
