The photo above of the September 4th filming was posted on an online with the message, "After the 'Dream Team' filming, a polite idol picks up trash, Seyong." It was revealed that another group's fan who visited the set saw Seyong picking up litter and made sure to capture the praiseworthy moment.
The original poster wrote, "After filming, I wanted to stay a bit longer, so I hung around to watch the set. I was touched after I saw Seyong helping the clean up crew."
A rep from MYNAME's agency responded, "We didn't know at the time of filming. We found out later when it was posted online. Seyong is usually very polite. He was a bit shy after finding out about this."
Good job, Seyong!
