Kim Heechul is bringing back the “SoHeeChul” feels!

On March 3, the Super Junior member shared photos that he took with Ahn So Hee while filming “Ask Us Anything.” Kim Heechul fondly wrote as the caption, “King wang zzang [the best] mandu [dumplings] Ahn So Hee.”

“Mandu So Hee” is a nickname that fans called Ahn So Hee back in her Wonder Girls days when she had adorable cheeks resembling “dumplings.”

After adding the words “Ask Us Anything,” “So Hee,” “SoHeeChul,” “unicorn,” and “oasis” in hashtags, Kim Heechul wrote, “It was my first time seeing her since ‘Come To Play’ back in 2010,” referring to an episode of the old variety show “Come To Play” where members of Super Junior and Wonder Girls appeared as guests.

“I even sang ‘Let You Go’ for her back then,” he added, referring to the time he serenaded Ahn So Hee with a TRAX song on a “Family Outing” episode eight years ago.

The episode of “Ask Us Anything” featuring Ahn So Hee will air on March 3 at 9 p.m. KST. You can check out the preview here!
