Sung Joon is the perfect pretty boy for "InStyle".

Wearing paster colored suits and outfits, Sung Joon exuded a manly yet chic aura throughout the shoot. His facial expressions and model-like poses drew as much attention as his handsome curly hair.

During the interview, he shared a hobby that he took up after finishing the filming for "I Need Romance 3". He said, "I bought a bicycle."

"For a month, I cycled my way from Yangjae all the way to Apgujeong. I pushed myself to the limit while biking that my body ached too much and I lost more weight compared to when I was on a diet for the drama," he shared.

On the topic of his acting, Sung Joon shared that he used to think of himself as a terrible actor. He said, "In my debut drama 'White Christmas', I really couldn't act. I challenged myself to get better because of it."

"I studied how to act, but in the middle of my desperation, I learned how to have fun and enjoy acting," he added.

"In the future, I hope to be able to act in a realistic and true-to-life production that captures the hearts of the viewers, just like Matther McConaughey's character in 'Dallas Buyers' Club'," he concluded.
