I found the other 성충문구 big stationary store downtown. It was closed, forever. And then minutes later my bike chain broke and fell off. Luckily there was a bike store close by and 5 minutes and 15,000 won later, I had a new bike chain. First time that's ever happened.
Then I stopped for bibimbap. And it came with beef, which doesn't happen often. So I got to scoop that out before enjoying. It wasn't looking like a good day.
