On May 12, the singer took to her personal Instagram account to share images of her visiting Key while he serves his mandatory military service. In the pictures, both idols are fresh-faced and in good spirits as they smile for the camera.

"Our Kibum, he even looks good in a military uniform," BoA gushed, finishing the caption off with a promise to Key that she would come back again.

Meanwhile, Key enlisted in the military on March 4, entering through a training camp in Nonsan. He is currently a member of the military band.
