You broke up with Matthew 6 months ago and are now dating Nicolas

As you walk through the hallway you see Matthew in his locker, you keep walking. A few seconds later you feel someone holding your arm softly and when you turn around you see Matthew

Matthew: Can we talk?

You look at him thinking if you should or not listen to him, but suddenly Nicolas hugs you from behind

Nicolas: Hey dear..I was looking for you.. He kiss your cheeks and Matthew clenches his jaw
