BoA and U-Know Yunho revealed a picture together.

Today, BoA posted on her Instagram, "Yunho that made a surprise visit to the waiting room! We both looked so tired so I'm posting it again after a little bit of editing. Because our Yunho is precious. Good to see you, Yunho" along with a picture.

In the picture, Yunho is wearing a white stage outfit and has his arm around BoA.

Internet users who saw this commented, "They look really close," "They're both so good looking," etc.
