James: He picks you up and spins you around before you go to class.

Sirius: You two sit in the car and dance to your favourite songs while waiting for your friends to join you.

Remus: He pinches your nose when you two are being affectionate and he feels flustered.

Peter: He always likes to goof around when you are doing things like baking, painting and or creating something.

Regulus: You two dance and he picks you up, twirling you while admiring how beautiful you are.

Lily:  You two put your hands together to create a love heart (mostly to make your friends cringe) but its become your signature thing so you both pose for a picture so you have evidence of it.

Marlene: When you go to leave for class, one of you always pulls the other back and kisses them again.
