You were sneaking in the Slytherin 'living room'. You decided to do that since you have been dared by Fred and George to do that. You were a scared to be found out by professor Snape or worse so you stay silent. You were also thrilled since that could give you the opportunity to see Draco or Blaise without any risk.

Suddenly, as your turn to leave because you hear a sound, you feel a hand on your right shoulder. You turn to see who it is : Draco

"You will have some explaining to do.."
