Singer BoA opened up about her complaints.

On May 29, BoA made her appearance on KBS 'Win Win' to talk about her trainee days in SM Entertainment.

In the show, BoA was asked "Did you ever get in trouble during your trainee days?" She responded "I always heard that I should lose weight. I start dieting from junior high.”

She added "How can you grow when you start dieting at such a young age? It's given that I didn't grow much. I think it will be a lifelong regret.”
