With his 27th birthday ahead on December 1, the handsome idol star shared on his Twitter, "This is embarrassing, but I wanted to tell you something concerning my birthday. It's not a very special day, but I'm thankful that so many people think of me every year. I've always only taken on my birthday, and this time, I want to volunteer for a coal briquette charity with you all. Please don't hesitate to contact me!"

Rather than a party or fan meeting, Siwan personally decided that he'd like to donate his time helping people who need coal briquettes this cold season and invited his fans along.

What a great guy!
