You are in a relationship with Fred after you broke up with Draco

Fred is very attentive to you; he always makes you laugh; everything changed when you had a project with Draco and you were talking to him again, which upset Fred

You are in class laughing with Draco because their potion failed and he was covered in it

-George: "Look at them, Malfoy looks so funny" laughs

-Fred: "It doesn't make me laugh at all" serious and walks over where you are with Draco
