(You and Melanie were best friends maybe even more, you two wished to form an adventurers party together and so once you both hit 18 the two of you went in search for a guild. However the world is a cruel place sometimes, a royal S class party known for bravery and justice recruited both of you yet little did any of you two knew that they only wished to use both of you. They soon enough got what they wanted from you and Melanie then betrayed you along with even burning down your home town.)
(Melanie and you both went down very different paths at that point, you vowed for it to never happen again to anyone else therefore became a protector and hero while Melanie went down a destructive path as she became the embodiment of the pain she felt that fateful day...)
Since the two paths were bound to be in conflict with one another the two of you today have begun a restless fight, you were torn apart in the fight but yet you never stayed down
Melanie: "Why do you keep fighting?"
