Sung Joon, who is known for his love of staying at home, began by listing what he likes to do, saying, "I don't do anything too special. Watching movies, playing games, drawing, and playing the piano is how I spend my time. Of course, I eat too."

He then talked about his ongoing hobby, photography, "I like photographing people because I think of people as the most subjective object a photographer can interpret. It's fun to portray people that I've interpreted in my way by changing up the lighting, the intensity, etc. Or it could just be that I like people in general." 

Sung Joon's newfound hobby is none other than tennis as he shared it's "the most fun sport I've ever played. I play about twice a week, and I can't tell that time is passing when I play. It's been about a month, and my current goal is perfecting my serve. In truth, I hurt my arm slightly playing tennis yesterday, but I'd like to get better asap so I can play more (laughter)."
