SoulSwap- an Undertale AU fanstory

This is about my Undertale AU, SoulSwap. It is about River, who falls on purpose in the Underground, three months after the Barrier was broken. She pretends having a silver soul which trait was Carefulness, but she actually has aqua-blue. It means Confidence. She gets really close with the the others, and lives with Asriel, Chara and Frisk as siblings. Toriel takes care of her. She goes to school, and they live in the Great Home, where all their monster friends can stay when they feel like.
She can change her soul in every color and trait, but one part can't be changed... the hatred, which cropped up during her terrible childhood, which wasn't as fun since she was six and discovered she has fire power, the power to revive every single soul, and create AU's. SoulSwap is her birth au, but it is empty. Nobody has that gift like her, so it is all empty.
How will her life go after the fall? Read on to discover

Ps. My first story, so don't judge me.
