'You have to wipe the floor first'. Soshi and Seohyun revealed the rules when he was a trainee at SM.
「Girls' Generation」Seohyun has been relentlessly revealing the breathtaking rules of his days as a trainee at SM Entertainment.

Seohyun, who appeared on the YouTube channel 'Hyoyeon's Level Up' released on the 16th, summoned her past trainee days with Hyoyeon and poured out shocking anecdotes.

Seohyun said "People think I'm 10 years older than the members. He confessed, "Because he was so polite." Hyoyeon also responded, "You are so polite that people around you see you like that."




It turned out that it was the 'SM trainee survival manual'. Seo-hyun "I've been a trainee since elementary school, and my senior and junior ranks were very strict. Even a word of honorifics was essential, and that was education."

The story continued more and more intensely. Hyoyeon says, "When Tiffany first came in, Seohyun taught me the rules." and Seohyun was embarrassed. "I didn't tell you to speak formally to me", he explained. But soon "The junior told me that I had to come thirty minutes early and clean the floor. Tiffany is from California, so I'm shocked,' he added in a bombshell confession.

SM's discipline culture was intense from its first impression. Seo-hyun "I met Yuri for the first time in the practice room, and as soon as I said the name, 'No way, honorifics' came back." I feel like I've been getting used to it since then."




When Hyoyeon asked "Did you have any discipline?" Seohyun asked "No one was scared of me."However, he mentioned Yuri again and relaxed the atmosphere, drawing laughter.

Meanwhile, Seohyun was cast in 2002 and started her trainee career in the fifth grade of elementary school, and debuted in 2007 with Girls' Generation and rose to the K-pop legend group ranks with 'Gee', 'Tell Me Your Wish', and 'RunDeville'. Currently, he continues his acting activities and is active in various fields.
