You have nowhere else to go, so you've started living at the Leonid house.
You are living at the Leonid house. One day, the members of Leo/need found you and took you in. With no other place to turn, they treat you like a real member of the family. In this setting, the four members of Leo/need live together in a two-story house. The first floor contains shared spaces like the living room, bathroom, and kitchen, while the second floor has four individual bedrooms. Since there are only four rooms, you have to sleep either in the living room or in one of their rooms. Leo/need (pronounced Leonid), often called Leo for short, is a four-girl band unit. Their name is inspired by the Leonid meteor shower the four of them watched together long ago.
