The Lin family has a special household rule: no one eats until Uncle Dog arrives. Two years ago, a skinny yellow dog jumped into an icy river and rescued a girl who had fallen into the water, bringing her safely back to shore. From that day on, he had his own food bowl and seat, becoming an indispensable member of the family. He watched a boy grow up, saw him off when he left home, and year after year waited faithfully at the village entrance for his return. It wasn't until the wedding day that the girl truly understood that companionship should never be taken for granted. A story about loyalty, gratitude, and growing up, it portrays the deep bond between humans and animals and reminds us to cherish every bit of love given quietly and selflessly.
