Explanation:

First person point of view is a mode of descriptive essay or storytelling in which an author expresses the thoughts and emotions of a character as if it were his own.

In first person point of view, the readers are able to know what the character is thinking, what he is feeling and how his character is developed. Use of pronouns like "I", "We", etc are used.

First person point of view helps the readers/viewers understand the character better.

Below is an example of first person point of view storytelling,

"I looked across the room and couldn't recognise the wreck that was once my room.

I remember my mum tucking me I bed every night, hearing my father's rocking chair as he smoked his cigar and cracked jokes with his loud friends. Now, everything is gone"

From the example above the reader is able to understand the feelings of the character and know exactly what he's thinking.
