Tiffany talked about showing Lee Soo Man her performance!
She had an interview with 'Entertainment Relay' about her solo release. Because it's her first solo album even though she debuted 10 years ago, the interviewer said she was a 'secondhand' rookie. She laughed and said, "I've never heard that term before! I'm still a rookie."
On her debut, she said, "I practiced the choreography for 6 hours and recorded for 2-4 hours [every day]. I went home, listened, and repeated the process. I had to get it confirmed by the label. I was practicing one day and Lee Soo Man said he was going to come see how I was doing. It was my first time showing him the choreography since 2007. Usually, he comments about the performance, but he applauded me. He told me that I worked hard, so I'd be able to succeed no matter what."
