On October 31, Heo Sung Tae guested on SBS' television show 'My Little Old Boy'.
Heo Sung Tae said, "Well, my life is no different though. I just repeat the same activities every day, so... I go home, then work. That's all I do, so it's the same."
He continued, "But I think I feel how popular the series is when I open my Instagram. I had like 10,000 Instagram followers, but now I have like 2.2 million followers. It's insane. My mom loves it."
Then, Heo Sung Tae talked about some people at a restaurant being surprised to see him.
He commented, "I think it's because of my roles in movies and 'Squid Game'. Some people find me scary."
The actor answered, "Oh yes, there is. I actually have a fear of heights. So, it was really hard for me to film 'Glass Stepping Stones' scenes."
He went on, "Because my character 'Deok-su' is a fearless guy, I had to act like I wasn't scared at all, but I was frightened to bits."
He added, "I shook in fear when the cameras weren't rolling. Then as soon as they began to roll, I acted as if I wasn't scared."
