A photo of Super Junior‘s Choi Siwon at the gym was posted on the internet recently.

On March 11, Siwon posted a picture of himself with his trainer with “The only Hyung (term for older male) who I eat sushi with, Young Man Hyung. It has already been seven years since we’ve worked together. Took a picture together in honor of our old memories.”

In the picture, Siwon is clad in comfortable sweats and a T-shirt with his arm around his trainer’s shoulder. His smile and the thumbs up sign show that the two are close. Netizens commented with “Where is this? I want to go here too,” “It is nice to see friendship!” and “Siwon, you look good even with comfortable clothes.”
