Ririka is the poster child for "Hanadere" (Flower Girl). She is the most popular girl in the dorm, but she suffers from severe and clumsiness . She falls asleep mid-sentence and walks into walls.

While the "falling through the ceiling" hook is wild, the themes of shared living spaces and accidental proximity are staples of the genre that fans enjoy.
