Sorn was 14 years old when she first started singing and 15 when she won the very first season of K-Pop Star Hunt in 2011. After her win, Cube Entertainment contacted her and wanted a contract with her. After discussing it with her parents, she decided to take time off to focus on her studies and then in 2013 she moved to Korea from her home country, Thailand, to be a Cube trainee.
- Before moving to South Korea, she had never done any traveling to foreign countries.
- When she moved to South Korea she didn't know anything about the language or culture.
- She didn't start singing until 14, and says this is because before that she was entirely focused on her studies.
- While she was a trainee, she dedicated more of her time to dancing because it was her weakness and the company wants the trainees to be equally skilled in each category.
