Evan Hansen is an angel. He was responsible for watching over other angels who had been misguided, and he helped them come back to God, even though he was, and still is, an atheist angel. He has lived like this for 238 years, but one day a special guardian case comes up, and he decides to take it after being stuck in the same position for over 200 years. When he landed on Earth he thought this would be easy, despite his lack of experience in the guardian angel field of work. Evan works with his human, spending the nights with him talking about their lives, and becoming friends, the one thing he feared happening happened. He fell for his human, and he knew that his boss up above would not be pleased to hear this.
