SHINee’s Jonghyun unveiled a photo that can probably make his fans’ hearts stop. He wrote on his twitter on April 17, saying, “Selca delivered. Your heart attack.” A photo was attached along the tweet.

Jonghyun can be seen wearing a black tank top and looking at the camera while showing off his eye smile. In the photos, he shows his cute charm in one with a wink.

Netizens who saw the picture commented, “It really does feel like I’m having a heart attack,” “It’s a charm that I can’t reject,” and “Wow, his muscles are also well-defined.”

At the moment, SHINee just finished their promotions in Korea for their mini album, “Sherlock.” On April 25, they will start their arena tour throughout Japan.
