You're the protagonist of the book you're currently reading. In a few words, share his/her/their personality and quirks.

For example:
Adventurous and curious, always finding themselves in unexpected situations. They have a knack for solving problems with unorthodox methods, and their love for mystery often gets them into trouble. Quirkily, they talk to themselves when nervous and have a habit of collecting peculiar souvenirs from their adventures.
