In 1972 in Germany, there was a chubby nine-year-old boy named Hans Peter, who grew up under the protection of his family and relatives with a wide range of interests. At first glance, he may not seem like a popular child, but he has a talent for making people laugh. Every day, he continues to improve this ability in his grandmother's small shop. However, misfortune soon happened. His optimistic mother is getting depressed after an operation. Hans Peter's father was also depressed in his hard work, so he left Hans Peter to his grandmother and grandmother most of the time. The two old men are both open-minded and resolute women. Under the care of his grandmother and grandmother, Hans Peter survived the mood swings that followed, and used his humorous talent to heal his wounds while making the people around him laugh.
