BoA might have let slip that she's slightly interested in actor Lee Jong Suk.

On the final episode of SBS' 'Thank You', BoA, Super Junior's Siwon, and actor Son Hyun Joo appeared as guests. While BoA invited Siwon on an outing for the show, Son Hyun Joo invited Song Joong Ki, Jo In Sung, Jang Hyuk, and Yoo Hae Jin. Despite his multiple calls, only Yoo Hae Jin showed up. 

Son Hyun Joo explained, "I heard that BoA is a fan of Song Joong Ki, so that's why I had them talk to each other over the phone." However, another rising actor had already gotten BoA's attention. 

She asked, "Do you happen to know Lee Jong Suk?"

Her question has viewers wondering if she's had her eye on him. Do you think BoA and Lee Jong Suk would make a cute couple?
