His agency released a photo today of Sungmin, who plays the role of Jin Goo, and his co-star Lee Young Yoo, and it's been causing a lot of fans to get curious about what kind of relationship they have in the drama.

Sungmin stated, "It's my first drama filming, and because I'm lacking in a lot of things and I'm nervous, I was worried that I'd hinder everyone. But the director and staff all supported and helped me out, so I filmed with a thankful heart. I'm also learning a lot during filming, so I'll make sure to show you a more advanced side of myself in the future."

'That Kind of Relationship' premieres on October 9 KST!
