Interest (emotion)

Interest is a feeling or emotion that causes attention to focus on an object, event, or process.^[1] It can be someone focusing on something because of their curiosity. It can also mean someone liking something.

The emotion of interest does have its own face expression, such as having their pupils grow.^[2]^[3]
