It's a rural area although Amori isn't small, but nobody came to check after Ruri death, must have been an accident where she couldn't say anyone she has a child back in home, but then again he attended to school...
Suzuka was already in Amori when Ruri called, but didn't came to visit at least for 3 days, Fuusuke was starving not only blood for very long...
Wonder how Ruri died and what happened to her husband.
