The good and bads of Seoul subway system

So the subway here is clean.
Yes. Clean.
1000% cleaner than the one in Paris.
And it is super cool here.
Awesome air conditioning available here.

But, it isnt friendly to foreigners. They cant understand most of the announcement. Why? B'cuz it is mostly in Korean.

So today i experienced some foreigner desperately looking for help.

Our subway needed some quick fox or rest or whatever, so it had to stop and go to the garage(?).
If that happens, all passengers should get off the train.

B'cuz the announcement was in korean only, he was the only one who stayed in the train.

I wanted to go to him and say to come out, but because there was so many people around me, i just beckoned him to come out. He did.

I just felt sorry for no reason.

I mean, just.
