Perhaps the scariest part is when the kid is alone in their room, sick with mono, and starts to see or hear things that they can't explain. The feeling of being isolated because of the illness and then having to face something unknown and potentially dangerous is really frightening. It's like being in a vulnerable state and having no escape from whatever is causing the fear. Also, if there are any moments where the kid is physically interacted with by the unknown entity, like feeling a cold touch or something grabbing them, that would be extremely scary.
If we assume a general plot for this story, one of the scariest parts could be when the kid realizes that the strange things happening around them are not just due to their mono - induced delirium. When they start to understand that there's something truly malevolent at work, it's a terrifying moment.

But without more details, it's hard to tell the full story.
One of the scariest elements is how the game world transforms into a really disturbing and nightmarish place once the watch is involved.

The way the ghosts interact with the living in Creepypasta True Ghost Stories can be really terrifying. For example, in stories where ghosts manipulate objects around people. They might move things around in a room while someone is sleeping, or turn on appliances unexpectedly. It gives a feeling that the ghosts are toying with the living, and that there's no escape from their influence. Also, the sudden appearances of ghosts, like a face suddenly showing up in a mirror or a figure emerging from a wall, are extremely scary.

Isolation is a key scary element. Many creepypasta stories take place in lonely settings such as deep in the forest in Slenderman tales or in an empty, haunted house.

This feeling of being alone and vulnerable in the face of something terrifying is what makes these stories so scary.
The fact that megladons are extinct in real life but still so menacing in stories adds to the scariness.
