Here is my character idea, I hope it's ok!
Yelena Solova is just nineteen, she's daughter of a Russian diplomat. She wants, very much, for working in the fashion industry. But she's spoiled rich girl, she doesn't ever work hard before, or at an office. She does want doing a good job, and pleasing her boss, but she gets frustrated easy. She pouts and throws tantrums, when she doesn't get her way. And, she likes flirting with people, for getting them doing her work!
Yelena loves to party, she maybe drinks too much when she goes out. She loves both boys and girls, no preferences. She never falls in love before, but has many, many one nights stands. She is very playful, and sweet, with her friends. She talks before she thinks, sometimes, that gets her in trouble! And she's exhibitionist, too, which is fun, but also gets her in trouble!
