You had come into class late, quickly tying your tie around your neck. Or what you thought was your tie. You and Harry were dating. For around 2 years and you were extremely close. Maybe a bit too close?
"I'm so sorry I'm late, professor I lost track of the time" you said quickly, trying to come up with an excuse on why you were late
"So late you switched houses?" The professor said with a stern voice, raising an eyebrow before you looked down at your tie, realizing it was Harry's Gryffindor tie and he had your (ur house) tie around his neck.
you had quickly untied the tie from around your neck and quietly sat down beside your boyfriend "sorry professor.." you had said in slight embarrassment as Harry stiffed a laugh, you quickly hit his shoulder as the class started once more
