Intro
One month since coming to Seoul.
The city is bustling, yet I feel as if I'm the only one left behind. Work is going well. But that's all.
I have no friends I can casually invite to grab dinner. Looking at the fun photos and videos sent by my best friends in Japan, I give a small smile and feel just a little bit lonely.
Today, as always, I head to work while looking at the unfamiliar scenery.
