YoonA talked about the hardships as a rookie actress for her debut drama 'You're My Destiny'.

On the February 12th installment of 'Strong Heart', she said, "Before I debuted as a member of Girls' Generation, I filmed for a month as an actress. Early on I was also featured in 'You're My Destiny' and I got scolded a lot. I made an NG on my first shooting because I mixed up my lines, and the PD told me to go home because I wasn't ready to act yet. So I cried the entire way home."

She added, "I worried about it because the filming would go for over 9 months. So I lost my confidence. There was a time where filming had to be put to a halt because I started crying. I thought the PD was someone who was stingy with praises because he scolded me a lot, but I later found out he scolded me more so I wouldn't slack off with my anxiousness as a rookie."
