The main character comes to work part-time at a ranch and takes care of 16 Holstein cows and their calves. He has to chase the cows with his dog, milk the cows, feed them, and carry the milk in buckets slowly without spilling. You can also take a car to explore and talk to the villagers. Together with the owner, breeders, veterinarians, and industrial technicians, you will make the farm prosperous. If there is too much feces, the ranch will be shut down if the animals get sick. Also, this hero sometimes loses motivation to work. At such times, sleeping well at home and drinking milk directly from the cows will increase his motivation. It is necessary to avoid submitting a letter of resignation.
