In the episode of the SBS talk show 'Strong Heart' that was revealed on the 28th of August, the guests that made an appearance included Hong Seok Chun, Im Ho, Hyun Mi, Han Hye Jin, Kim Yoo Mi, Kim Ji Won, Kwang Hee, and Sulli.
In this episode, Sulli revealed, "I am 169cm and I am not over 170cm but since there are many people who put their heights taller than they really are on their online profiles, I get many misunderstandings when I stand next to them.
Sulli continued, "My tall height is my complex. I want to be able to be completely embraced by a man. I am jealous of small people." After, a machine that measures height was brought out. Sulli's height was measured, and her height turned out to be 169.8cm. Just like she said, her height was not over 170cm.
On the other hand, Kwang Hee's height on his online profile was written as 179cm but his real height was 173.6cm. Kwang Hee said, "Strong Heart is too much," drawing much laughter.
