Did you know Siwon has a refrigerator magnet collection? Youngest Super Junior member Kyuhyun knows! And not only that, but according to one of Siwon's recent tweets, every time Kyuhyun travels anywhere, he's sure to pick up a magnet for Siwon's collection. How thoughtful!

Siwon tweeted a picture of the latest magnet, evidently from a trip to Chile:

How sweet is that?
