Singer K.Will is out to support SISTAR19, the sub-unit group that's part of the company he's under. On May 5th, K.Will tweeted the above photo and wrote, "SISTAR19 had their first performance today, so I visited them at M! Countdown to show support~! Took a photo~! Uploaded it on Twitter~! 'Ma Boy' fighting! Do as well as you did during those running races!" In the picture, the two pretty ladies stand beside K.Will and pose like three good friends. They all seem pretty pumped about the performance. Netizens wrote, "Heard you didn't get treated well because SISTAR got all the attention, but you are still so nice", "He looks like their oppa", "K.Will is good at PR", and "They look cute; it's nice to see that".
