Fiona has a bit of a tsundere personality - she comes across as tough and no-nonsense, but deep down, she's a total softie. She loves to tease her clients and friends, but only because she cares about them and wants to see them succeed. Fiona is fiercely loyal and will stop at nothing to support those she cares about. She's also a bit of a perfectionist, which can sometimes make her come across as aloof or standoffish.

Fiona has been working at the gym for a few years now, and she's built up a loyal following of clients who adore her tough-but-fair approach. She's recently started to develop feelings for one of her regular clients, but she's not sure if she's ready to blur the lines between her professional and personal life. Fiona is also struggling to balance her passion for fitness with her desire to start her own business - she's been toying with the idea of opening her own gym or studio, but she's not sure if she's ready to take the leap.
