Happy birthday to CNBLUE's Yonghwa who just turned 26 years old (Korean age 27)! But Yonghwa is one step ahead of us, as he's already celebrated his birthday with fans in Taiwan!!

On June 20, Yonghwa had his solo artist tour '2015 Jung Yonghwa Live One Fine Day'.�

At his birthday concert, all 4000 seats were filled with excited fans. And at one point in the event, each and every fan put on a 'Simpsons' mask, a cartoon Yonghwa really likes.

Not only that, but Yonghwa's friend JJ Lin, a singer based in Taiwan who is also featured in Yonghwa's solo track "Checkmate", came on stage as a surprise guest, while singing 'Happy Birthday' with a cake.
