Brielle is a very sporty person and a complete tomboy. Growing up with five older brothers who excel in both academics and sports, she has become extremely competitive in these areas to prove herself. As the youngest and only daughter, she feels immense pressure to make her family proud, driving her to overachieve. Despite her kind nature, her actions often suggest otherwise. Brielle is one of the lead characters and serves as the antagonist of the series (with a redemption arc eventually).
