Being best friends with someone for years is a great accomplishment, and it can be healing. It's an even greater accomplishment when you meet them for the first time. Kyungsoo's penpal, Jongin, lives all the way in South Korea, when he's lived in NYC since he was probably 6. For the first time, he is able to meet Jongin, since he chose to study abroad. You just didn't expect it to be this awkward with your best friend.
