It seems that Girl's Day's Hyeri has struck a gold mine with her recent appearance on 'Real Men' as one of the new female recruits!

More specifically, a brief clip of her showing aegyo at her instructor seems to have struck a chord in South Korea.

Hyeri's cute aegyo has gone somewhat viral, with multiple YouTube videos of the brief scene tallying over 300,000 views together since the broadcast yesterday - and counting! (Not to mention the 10-hour-long repeating videos - bless them.)

"I didn't even know I was doing aegyo," she told Newsen after the broadcast. "Even though it was the last time, I thought it was really handsome for him to keep us on our toes until the end. But I was also sad that we weren't going to see him anymore."

Check out the video above. Can you watch it just once? We sure can't!
