Video on Demand section of After School Club's website. You might as well check the other episodes too.
After School Club airs live every Wednesday on Arirang TV at 5pm. You can chat with your favorite Korean stars/ idols so the format is really unique. It's all in English to especially cater to international fans!
I have talked to everyone in the group already several times and based on that I could probably give some insights on their character. TK is surprisingly fun to talk to. At the start he would tend to be really quite and shy but when he gets to know you he'd say a lot. He even utters lots of English words with good pronunciation. hehe Ray on the other hand is very bubbly. Every time I take a photo of him he'd give suggestions on how he want it to appear. Like he'd say can you make this one cute? The last time he told me to take a "sophisticated man type of photo" of him. So I was like...how'd I do that? lol
