Y/n l/n just wanted to live an everyday life but not everyone gets that life. Recently Killer has gained a soft spot for y/n and will do anything her, even if he has to murder somebody to have her for himself...

You've fell into a dark hole and met Flowey, you and Flowey acted like enemies and you wanted to be friends. You met Toriel and had to leave, but you hated your life in the surface. You ended up in the snowed woods and heard kids playing, but you were cold as HELL. You rubbed your hand for warmth but it created a (F/C) flame.
