I was about to transfer to Line 9, but suddenly 5 minutes was 21 minutes, so I came quickly and it’s coming in So I said “Yay” and it’s been 20 minutes since I got it wrong Why are you on strike with the car in front of you for 30 minutes? It’s annoying I don’t know if the regular service was good. I remember getting caught while riding a 900-won train and asking for service
