Hoshi Furu Makiba!

Mozu Sousuke is fired from his job as an model and half-forced to move to a farm in Hokkaido. As someone who's always lived in the city, the shift in schedules, the heavy labour, the lack of contact with the outside world, the cold, the temperamental livestock, and the rather fierce little sister are quite the ordeal.
Note: Includes the one-shot "Kimi to Meguru Sekai" (キミとめぐる世界).
