The singer held his solo concert, titled 'Naughty Party - Strip,' this past weekend at the SK Olympic Handball Gymnasium, and many artists under his label dropped by to show their support! 

Among them were 2PM, 2AM, DAY6, and several darling TWICE members. The picture that catches our eye in particular is that of J.Y. Park and Sohee in a chummy pose, holding up peace signs. It's good to see that J.Y. Park and Sohee have maintained a close relationship even after her departure from Wonder Girls! And of course, it's good to see Sohee looking gorgeous as usual.
