She's been a face in many beauty pageants. It started out when she's 20 because of her fascination with watching "Miss Universe", and dreamed of winning the title someday. She joined an agency to train with so much excitement. However, it wasn't the easiest as she expected.
The pressure is too high while training. Weight maintenance is very important which led to her depriving herself from eating the foods she loves to eat. But the worst thing is seeing her colleagues exerting too much with losing weight until they lost their energy, and got hospitalized.
Some of the trainees became either anorexic and bulimic, while others became depressed ending up consulting specialists to treat mental illness. The harsh words coming from the trainers isn't healthy for anyone's mental health, as it's considerably bullying.
The hypocrisy of those people around is too much that she couldn't handle anymore. They defend their bullying as constructive criticisms, which in fact isn't. "Question and Answer" training is full of hypocrisy surrounding the topic of "inner beauty" when they were imposed to become beautiful. That led to her decision to leave the training, and went to school to study Psychology.
