Eva Caballero, 23, divorced, of Spanish origins.
She's still friends with her ex-husband, she has no siblings and no contact with any of her family.
She's decided to start her studies again.
Therefore, here you have the first student to appear in the story. Also the last character with black hair. (Yes, you had the three of them in a row).

Not a lot more to say about her. She's a very mature woman, while other students are still kids in their heads. She's enjoying studying English, and loves translating.
She lives alone in a small apartment her ex-husband gave her (he's a freelance in real estate and is very rich).

And... that's all I can think of right now Hope you like her.
