Bel was born to a wealthy family in Lebeaux on April 16, 2001. For the first few years of her life, she's been given all the attention due to being the younger child. She was spoiled by her father, cared for by her mother, and taught by her brother. She had a normal childhood, until her baby sister came along. Cleo was adopted into the de la Vega family and the attention shifted from Bel to Cleo. Bel did not understand what happened and was confused. The attention was all on Cleo now and like any other sibling, she became jealous. Her parents started neglecting her when in came to her wants. The only people who truly understood her were her siblings and friends.
Her friends learned about what was going on back in Bel's home and gave her the worst possible advice ever: to become rebellious. Since most of her friends were middle children, she thought I just had to work. She started sneaking back in when she came home late, she stopped following rules, and she just became rebellious and that ruined her goody-two shoes reputation. Her parents became aware of her behavior and tried talking to her about it, but she wouldn't open up. She disagreed with everything they suggested, and they decided it was best to be a lot more strict. Their decision made her worse as she then started sneaking out late at night. Her parents were now completely unaware of that, as Bel tries to hide that, which she is doing a pretty great job at. She learned how to lie to her parents and other people, and she became a lot more confident, getting less scared and paranoid unlike before.
Her parents then realized it was most likely because of the bad influence of her friends. When they were told Bel's friends were a bad influence on her, they were furious. They had always known her friends were trouble from the very beginning, but they had not said a word since they didn't want to be ones assuming, especially when there is a chance they would be wrong. When the summer came, Bel's parents made the decision of moving to Miduna Beach, far from her friends. They didn't let Bel know where they were moving, since they knew she would eventually tell her friends about it. She diagreed with their decision, but this time, they did not care. She was forced to stop communicating with her friends and to completely cut contact with everyone she knew in Lebeaux, much to her dismay.
Once they arrived at Miduna Beach, she became a lot more pessimistic and grumpy. She didn't make friends, she didn't try to reply to anyone, she shut everyone off. She still sneaks out from time to time, but she does her best to stay away from anyone who looked like they were friendly and could approach anyone with confidence. A few months later, however, she grew to love Miduna Beach. She had a few friends, and she started talking to her siblings again. She stopped talking to her parents, and has no plans of apologizing to them for acting quite horribly.
