Promise me No promises

Cut me up like a knife and I feel it deep in my bones.

Louis was raised in a abusive home, only having his little brother to call family. He works endlessly to make ends meet. He tries to take care of his anxiety ridden little brother while juggling multiple jobs as he tries to take care of himself, which is proving to be to much. He doesn't trust anyone, he's rude and feels that nobody could love him and deal with his luggage. How could they when he's lost his innocence long ago? He has nothing to give.

It takes one person to change the way you look at things. What happens when this person finds Louis and loves everything about him?

What happens when Louis doesn't care about love anymore and tells the person to get lost?

Baby, we can't see the bottom. It's so easy to fall for each other, I'm just hoping we catch one another.
