CNBLUE's Minhyuk surprised fans with his "date" with Super Junior's Donghae!

He set his Twitter followers on fire when he posted, "I'm on a date right now~ Who am I on a date with~?!?! If you guess right... you're a genius." Fans made their guesses, but none were able to give the right answer. 

Minhyuk assured his fans that his date was actually just a buddy by tweeting, "The answer isDonghae hyung~! A lot of wrong answers said Jungshin. Kekekeke."

The two idols seem to be celebrating Donghae's birthday, which is coming up on October 15.
