Two girls decide to take care of a dog together, sharing the daily tasks of feeding and playing. At first, the arrangement brings them closer, but a shift occurs when the dog begins to show a clear preference for one of them, lavishing her with affection. The other girl watches from the sidelines, her contentment replaced by a growing sense of exclusion.

As the dog's favoritism becomes more pronounced, the neglected girl's jealousy intensifies. She resents the bond between her friend and the pet, interpreting the animal's behavior as a rejection of her own efforts. Small tensions arise in their interactions, with the jealous girl making passive-aggressive comments or withdrawing from shared activities. The once-harmonious household becomes a stage for unspoken rivalry, where a simple pet has unwittingly become the catalyst for emotional conflict.

The story explores how a seemingly trivial source of jealousy can erode a friendship, testing the limits of patience and understanding as the two girls navigate their changing dynamics.
