Answer:
The reader needs to connect with the character. When a reader emotionally connects with the character, he gets engaged and interested in the story.
Step-by-step explanation:
If the reader knows the action of the story he will get more involved in resolving the end, by guessing or assuming.
If there isn’t an action that is noticed in the story, or that is unfamiliar to the reader, the reader can get bored and lose interest in the story.
