Leyla is portrayed by Scottish actress Freya Mavor.
Leyla was born to an upper-class family as the only child. Growing up, Leyla's parents completely spoiled her and she'd always get anything she wanted. In school, she was always a bitch. From kindergarten to now, she was feared by everyone in school, even her friends. However, the summer before ninth grade, she found her father with another woman, who wasn't her mother. This scarred her completely and caused her to be even worse to people in school, even people who did nothing to her. She's too scared to confront her dad about it, doesn't have the heart to tell her mom, and doesn't know what'll happen if she tells anyone in school, so she's completely lost.
Leyla is known in school for her tough exterior, however there's much more to her than that. She puts on a tough girl act because of her actual insecure and timid personality. She deeply cares what people think about her, and despite acting like she doesn't care about anyone except herself, she has a very strong sense of empathy for others.
Leyla has shoulder-length wavy blonde hair and large, bright blue eyes. Her skin is very pale and is covered in freckles. She stands at 5'6". Leyla's typical outfits consist of expensive sweaters, skinny jeans or a short skirt, and flats. She normally wears a normal amount of makeup, including eyeliner and lip gloss.
- She's of Polish, Irish, Scottish, Czech, and Ukrainian descent.
