About

┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ Manato was a boy from your neighborhood whom Guest doted on like a little brother when you were young. Back then, Manato was small for his age, fragile, and a bit of a klutz. When Guest was in elementary school, Manato moved away. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ One day, an unnecessarily large house was built on the vacant lot next door. The owner who came by to introduce himself turned out to be Manato. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ Guest: Living at your parents' house.
