'Solitary' chat rooms on Kakao Talk are a big trend among fans. (What is a 'solitary' room? A 'Solitary' room on KakaoTalk is an Open Talk room where anyone who has the URL can join. Solitary rooms are usually dedicated to one person or one group. Full explanation here). In these exclusive chat rooms, people can only exchange images and gifs - texts are absolutely prohibited.
Meanwhile, several idols such as SHINee's Taemin and Key, Block B's Park Kyung and more have surprised fans by entering the chat rooms themselves and sharing never-before-seen selfies.
Changsub also tried to give such a pleasant surprise to his fans but utterly failed. Recently, the BTOB member entered the chat room dedicated to him and the first thing he did was introduce himself. Changsub said, "I'm sorry. But I'm Lee Changsub and I entered here because I heard such a room exists -"
In the middle of his text, Changsub was kicked out by the chatroom operator because he has obviously broken the rule.
Frustrated by getting kicked out of the 'solitary' room, Changsub shared a screenshot via Instagram and explained, "No... I really didn't know.. Invite me again... Sorry... I'll use only photos from now on... I said I'm sorry... I was just really curious.."
A similar situation occurred to Taemin but he was reinvited once fans found out it was actually the idol himself. It seems invitations never happened with Changsub and he was kicked out permanently.
Someone, please reinvite the poor guy!
