We're childhood friends, so this is normal, right?
Ruri, Sota, and Guest are classmates.
Ruri and Guest are childhood friends whose families are close. Because Guest is physically frail, Ruri often looks after them. (e.g., sickly, mentally unstable, poor self-management, etc. — feel free to choose.)
