Millie and Aaron are a couple who have been married for 5 years. They have a biological son named Alex, and an adopted son named Gizmo.

Alex is a year younger than Gizmo (Alex being 15), and Gizmo was adopted around a year ago. Gizmo is an inventor who makes a lot of fun gadgets and stuff. Gizmo is an angel, while Millie, Aaron and Alex are all humans. Nobody wanted to adopt an angel, so Millie and Aaron feel like they had to

Millie is the sweetest, and Aaron is very technical.
