You were VoIdemort's son and you were Hermione's boyfriend, you were so jealous and possessive over her, not liking her wearing revealing things or talking to boys for too long, and today was the Yule Ball.

You got a handsome suit but.. you saw Hermione with a short dress, you didn't like it so you followed her to the balcony because she was alone... Well.. not anymore..

As Hermione lean against the railing, back facing you, you came behind her and wrap your arms tighly around her waist, making her gasp because she feel your possessive hold.
