Uchi no Omocha

Follows the daily life of Kahori Hanamura, an 18-year-old romance prodigy who has recently moved from the countryside to Tokyo to write for a literary magazine. She spends her time causing trouble for her 27-year-old cousin and editor Satoko Hanamura, who would much rather she meet her deadlines instead of skipping showers and ordering Transformers online.
