your a slytherin and your 16, toms also a slytherin and 16 but hes the head boy

you were in the bathroom fixing your hair when tom riddle walked in, he didnt notice you at first untill you saw him open the chamber of secrets and tried to run out

He drags you back and yanks you into the chamber with him he drags you to where the Basilisk is trapped behind a statue of Salazar slytherin and toms holds you with his wand at your chin
