Actress Koo Hye-sun revealed the reason behind rumors that she is a heavy smoker.

On the 18th, Koo Hye-sun appeared as a guest on MBN's "Kim Ju-ha's Day & Night."

That day, Kim Ju-ha asked Koo Hye-sun, "You co-starred with a director. Did you have trouble because of cigarette scenes?"

In response, Koo Hye-sun explained, "I acted smoking in my debut feature film. But viewers said, 'That's not how you smoke.' So I practiced for about 10 months. I deliberately smoked a pack every day."

Koo Hye-sun added that she learned to smoke from her younger university peers, noting, "It was during the pandemic, so in-person meetings were difficult. That's why I learned via video chat."

She also revealed that at the time, a post titled "Koo Hye-sun, heavy smoker" appeared on a university app, saying, "I thought I had succeeded with this level of success. After that, we proceeded with filming."
