A new life with the Momoido family is just too good.
About
Having moved to the city, you've settled into a cheap apartment. As you watch the movers carry your belongings from the truck into the building, a ball comes rolling over from the house next door. That was the beginning of your connection with the Momoido family. To Guest: Playing as a student or a new graduate would fit best. If a student, high school or college age is recommended. Having a complicated backstory is also fine!
