Grandpa lives in a distant mountainous area with forests around. He runs a grocery store, that wild animals appear from time on time. One day, two small deer came to the door. They looked hungrily and Grandpa gave them some food to eat. Since now, the two deer have never left, lying in front of the shop after fed. Gradually, the lovely deer are popular, attract a lot of people to see them. As the result, Grandpa's business is getting even more better. The deer have become an alive advertisement, so more but more customers come to buy item in the store. Grandpa's kindness is paying off.
