How can the 'humans become pets fanfiction' be made more engaging?

Involving other characters in an interesting way can make it more engaging. Maybe there's a character who is trying to understand what the baby is experiencing during hypnosis. They could be an older sibling or a parent. Their reactions and attempts to communicate with the baby can add depth to the story. Also, creating a sense of mystery around the hypnosis itself, like not revealing all at once why the baby was hypnotized or what the full extent of its effects are, can keep the readers hooked.

Adding a lot of vivid descriptions. For example, if the story is set in a forest, describe the lush greenery, the sounds of the animals, and the smell of the damp earth. This makes the setting more real for the readers.

Adding vivid descriptions of the emotions involved can make it more engaging. For example, describe the mother's fear, the father's anxiety.

To make a 'Naruto is heartbroken' fanfiction more engaging, focus on his emotions deeply. Describe how his heartbreak affects his daily life, like he might stop eating or training. Also, add some flashbacks to happier times to contrast with his current state.

By developing strong characters. Make Gamzee's character multi - dimensional, with his own hopes, fears and quirks. Also, create interesting antagonists if there are any involved in the abuse situation.

The idea of adapting to a new way of life is also significant. Humans in this fanfiction have to get used to living in enclosures or small spaces, and relying on their 'owners' for basic needs like food and shelter. It's a total change from their previous independent existence.

Add some mystery. For example, after the kiss, Merlin starts to have strange visions related to Arthur's future. This will keep the readers hooked as they try to figure out what these visions mean and how they are related to the kiss.

Their reactions to the strange relationship between the main characters can add depth and interest.

Involving some internal conflict within the characters can enhance the story. Batman might be conflicted because of his code of ethics and his role as a protector of Gotham, while Catwoman has her own motives and loyalties. Their kiss could be a moment of surrender in the face of these complex emotions, which would draw the reader in.
