Jang Geun Suk shared his tip on how to fight this year’s sweltering heat. On August 5, the star actor/singer wrote on his Twitter, “What…what? Korea is hotter than Thailand? Played tennis for 20 minutes but it got too hot, so I sat on a metal chair, but I almost burned myself.”

In the accompanying photo, Jang Geun Suk is seen shirtless, with a wet towel on top of his head. You can see sweat dripping down his forehead, and his grimacing look shows just how hot it was at the moment.

Netizens commented, “Jang Geun Suk’s facial expression says it all,” “Wow, he looks sexy with tanned skin,” and “I love this guy, he’s so real.”

Meanwhile, South Korea has been experiencing one of the hottest summers in recent memory, with daily temperatures reaching nearly 100 degrees Fahrenheit for two weeks straight. Weather forecasters say it’s the hottest summer since 1994 and Seoul’s average temperature this year has been the sixth highest in history.
