We guarantee this photo will make you go, 'WTF?' There's this photo taken of a sign from a recent BTS fan event that is circulating online. And at first glance, it looks like a regular, simple sign for a fan event for BTS' 'HwaYangYeonHwa Pt. 2'. 

But there's more. One of the last notes in the sign reads, "Yook Sungjae is unable to attend because of individual activities. We ask for your understanding."

Apparently the event coordinators for this event think BTOB's maknae Sungjae, is actually a member of BTS instead! But you should note that it's highly likely this photo has been edited with by a netizen, just to troll around.

Disclaimers like the one about Sungjae below are usually told to event coordinators directly from the artist's agency themselves. And obviously BTS' agency would not have mistaken Sungjae as one of their group's members.

Either way, Korean netizens are getting a hoot out of this photo. The netizen who posted the photo wrote, "The very last line kekeke...Sungjae can't make it because of individual activities...the fans' reaction...yes, of course Sungjae can't make it? It's so funny I could die...it's still so funny..."

Some of the top comments include:

"Crazy, kekekekeke, the reaction is even funnier...they're going crazy...pardon? Of course Sungjae won't be attending the event.....ha...okay...Sungjae is BTOB...aigoo." 

"If it was anything else, he could have been a guest but this is a fan signing, kekekeke."

"kekekeke, I'm seeing this correctly right? Since when was Sungjae in BTS..?
