My Magical Bodyguard

Cristoph Thompson has nothing left. His parents are divorced, his father is a good-for-nothing drunk, he's always getting bullied at school and, to make everything worse, he's homeless, even though his father has his own house and tons of money. One day, Cristoph decides to end everything with one slit right across his neck. Just before he decides to go through with it, he meets Elizabeth, a magical entity who soon helps Cristoph realize that there's more to life than he thinks.
