Fujieda Ryouko

Ryouko is the widow of apartment 503, living next door to Kouji and his dad, Akira.

By profession, Ryouko is a wedding dress designer that works for a wedding planning company. At home, she is the "mother" of the "family" that lives on the Florias apartment building's fifth floor. She apparently lost her husband many years before the story begins, since her daughter Koyuki makes no mention of her father, and Ryouko herself isn't really clinging to the memory of her dead husband.
