Fumi-chan no Rakuen

Eat, sleep, sex. Fumi is a novelist who has lost her passion for writing. Now she lives with her man in an old house in the countryside. Nighttime picnics, a dip in the river, harvesting vegetables - they eat delicious food, sleep well, and have sex whenever and wherever they feel like it. It's like a never-ending summer vacation.
