Kim Kwang Soo celebrated his birthday on Thursday with girl group Gang Kiz and the photo of the party scene was spread quickly through Twitter. The internet users who saw the photo on T-ARA DC Inside gallery and all entertainment boards responded variously to the situation.

They first had a question about the absence of T-ARA. One of the internet users said "Is T-ARA having self-reflection time? Is it now time for Gang Kiz?" and other said "After the withdrawal of Hwayoung, it's the first birthday but he spent with Gang Kiz." Also, some fans pointed out that it is not the right time to celebrate. Even though Hwayoung uploaded a photo 'bed self camera' with her twin sister and showed a better side but alot of internet users agree that it doesn't look good for the representative to already show the careless party. On the other hand, some said "T-ARA thing is just a case and birthday is a birthday. Why can't he have personal party?"

On the other hand, Gang Kiz is a seven member girl group with "Hyunbin's ex-girlfriend" Hwang Jihyung, "Rollco Girl" Lee Haein, and so on. They released an album last May.
