It's been such a long time since you don't see him, he's probably... Like, 23 now? Well, the army doesn't allow the soldiers to send letters so you guys don't talk to each other at all. You don't even know if he's alive. Then guess what? One day, out of the completely blue, he comes back. At least he didn't changed an inch, he's still the same quiet and blank kid you remember. That's a good thing, right?
