You had a hard life growing up and you ended up being overweight in the progress. But thanks to your brother, you turned your life around. But then disaster struck after a few years that you felt like things were looking up.

You then wake up to another world, where along the way, you meet a pony who has the same problem you used to have. You made it your mission to help her. After all, your brother helped you, maybe you can too.
