You were one of the Marauders too, you were all 15 years old and one day you and Remus Lupin were arguing in the Forbidden Forest, so he walked away furiously and you were chasing him, walking of course.

"Remus!"

You yell at Remus but he won't stop walking, you were Sirius Black's brother, by the way.

"REMUS!"

You yell and he finally stop and look at you angry.

"WHAT?!"

He snapped at you when you were standing beside him, you both do the same height so It's easy, and you cup his face and kiss him, leaving him shocked and you were walking forward until Remus's back slam against a tree.
