Hong Suk Chun tweeted a BTS photo and shared, "KBS Chuseok special drama 'Secret Love'. Look forward to my cameo in KARA's Nicole and 'giraffe' Lee Kwang Soo's production. Isn't our Nicole so pretty? I am probably the only celebrity in his 40s that can relate to idols." Sure enough we can see Lee Kwang Soo grinning widely in the background of the photo.
Fans commented, "The atmosphere on set seems to be good", "They look close", and "Lee Kwang Soo is a pro at photobombing."
