Soohyun from boy band U-KISS recently celebrated his 25th birthday, and despite being swamped with "Standing Still" promotions, his fellow members took some time to celebrate the leader on his big day!

"To our lovable leader Soohyun hyung!!!" Kiseop posted to his Twitter, along with a photo of a birthday cake. "Really truly congratulations for your birthday? I love you >_____<"

AJ also posted, "It's our Shun-leader birthday?! ?? Happy birthday! Don't be sick and stay healthy!"

Kevin simply posted a hashtag that had been trending at #1 on Twitter earlier - #UKISSSoohyunDay. Meanwhile, Hoon posted another angle of the festive birthday cake, which featured a likeness of the birthday boy along with colorful letters that spelled out 'SOOHYUN'. Eli kept his message short, simply saying, "Happy Birthday @ukissSH !!!!!^^".

Although he's already received plenty of goodwill for his big 2-5, we're sure he could use a little more - happy birthday, Soohyun!
