Girls' Generation's Seohyun shared a fun story about the strict rules and discipline trainees faced at SM Entertainment.
On April 16, Seohyun appeared in a new video on the ‘Hyo Yeon’s Level Up’ channel, where she recalled her early days as a trainee.
She said, “Unnie, do you remember? When we were in elementary school and became SM trainees, we had to use formal language with our seniors and juniors. It was the proper thing to do.”

She went on, “I remember the first time I met Yuri Unnie. She told me, ‘You can’t speak casually. You have to use formal language.’ From that moment, I followed that rule. I was a trainee for five years.”
When Hyo Yeon jokingly asked, “If a junior joined, would you have done the same?” Seohyun replied, “Actually, even Tiffany Unnie was my junior."

She added. "I didn’t make her use formal language, but I did tell her about the rules, like coming 30 minutes early and cleaning the floor.”
Hyo Yeon, who had lived abroad for a while, humorously imitated Tiffany, who didn’t quite understand Seohyun’s instructions, which made everyone laugh.
It’s clear that Seohyun fondly remembers her time as a trainee, where discipline and respect were highly valued, even with her fellow members.
