Here is my story spine!

Once upon a time, new guardian angel Samuel trains hard to finally get a human assignment.
Every day, Samuel works hard, and eventually comes out to be the best guardian angel in his class.
Until one day, Samuel is called to take on an assignment of a boy named Wyatt, whose previous guardian angel recently quit.
Because of that, Samuel learns that the last guardian angel quit because Wyatt is extremely reckless.
Because of that, Samuel tries his best to protect Wyatt, but becomes increasingly more worn out and frustrated as he continually throws himself into danger to protect a child who has no regard for his own safety and wellbeing.
Because of that, Samuel feels as though he has failed, and chooses to walk away from Wyatt.
Until finally, Samuel learns that Wyatt’s home life is really difficult and is the reason why the boy acts out. Samuel has a moment of sympathy for Wyatt, and chooses to keep helping him as a way to bring some safety to this boy’s life.
And ever since, Samuel finds value in protecting and comforting the troubled kid, without losing motivation or self confidence. Samuel learns that in the end, we shouldn’t judge others because we don’t know what they have been through; and even the most frustrating kid’s life has value.
