JYJ's Jaejoong collapsed during his Taiwanese concert.
..Or he pretended to, anyway. He collapsed after performing the rock song "Good Morning Night". The concert was halted and security and staff rushed to the stage, frightening and worrying all the fans who were present. However, Jaejoong got back up soon enough and the music started again, and fans were relieved to find out it was just an April's Fool's joke.
But he wasn't the only one with an April's Fool's joke. His fans also played one on him by holding up banners that said, "We're actually fans of Jaejoong's manager," and made Jaejoong burst out laughing. He brought his manager up on stage and the fans cheered his name.
Hopefully his fans are all right after that scare!
