On April 1, Ryeowook played a funny prank by giving his Twitter account a complete makeover, making it look like it was the account for EXO's D.O!  He changed his name to Do Kyung Soo (D.O's birth name) and changed the pictures accordingly, as well.

He then wrote, "Fighting to Baekhyun and Heechul's radio.  What is Ryeowook doing?" and, "I love you, Ryeowook," even including a D.O selca in that second message.

That's right - it appears to be a cute and harmless April Fool's Day joke!  Netizens said, "I was so surprised when I looked at Ryeowook's Twitter," "Suddenly turned into Do Kyung Soo's Twitter?  So I see it was an April Fool's joke," I was confused on Ryeowook's Twitter.  Ryeowook and D.O are cute," "I thought I was looking at the wrong Twitter.  D.O's a prankster," and more.

Were you confused and tricked by Ryeowook, too?
