Former ZE:A member Kwanghee revealed why he unfollowed Siwan.

On the October 5 KST episode of former ZE:A member Kwanghee's YouTube series 'Careet', CNBLUE's Yonghwa, Highlight's Doojoon, and former MBLAQ member Lee Joon made a guest appearance. Here, Yonghwa told Kwanghee, "I'm a little upset about something you have done to me in the past. You suddenly stopped following me on Instagram. Do you remember when I complained to you about this? You then followed me again, but you eventually unfollowed me afterwards. How could you do this to me?" 

In response, Kwanghee replied, "I just wanted to look cool at that time. You know how a lot of celebrities have zero followers on their Instagram accounts, right? I wanted to do that as well, so I just unfollowed everyone." He then awkwardly apologized to Yonghwa. When asked if he also unfollowed his former ZE:A member Siwan, Kwanghee hilariously replied, "Of course I did! I even told him directly that I was going to unfollow him before I unfollowed him. His follower count surpassed mine at some point and I was so upset. He's also going to be on the second season of 'Squid Game' and will have so many followers after the series gets released. I'm not sure if I can bare to see that with my own eyes!"
