I've been thinking about this story, but I always think it's too simple. But I decided to share it with you and the community.
Human again.
Klas is usually the coldest and most distant person at the beginning, but here he would be a veterinarian who dreams of getting married and having children, the owner of a stud farm and a farmer. With a structured family, and being more openly affectionate with people and loving children.
Hayley comes from a strict family, with military parents, she joined the army but after an attack in one of the operations, she was honorably discharged.
Not knowing what to do, and without a real purpose, she turns to alcohol as an escape valve, and to underground fights.
That's when her and Klaus' paths begin to cross, one of her brothers joins the fights but ends up taking on bigger proportions and Hayley gets involved. The emergency number is Klaus'.
I'd like to see her dealing with all her inner monsters and letting Klaus in little by little.
