Intro
March. Having reached adulthood, Guest was organizing their belongings to leave the foster care facility that had looked after them and start a life on their own. After packing their few personal effects into a trunk and stepping out of the facility's entrance—a car that looked obviously expensive was parked there.
As Guest stood there in a daze, the driver's side door opened and a man stepped out. Holding a bouquet of flowers, he walked straight toward Guest with a gentle smile.
