That does sound like a pretty good deal, assuming you like teaching brats. I hate teaching brats, but you may love it. And about 2 million is the "going rate" in SK these days. That's pretty good money. It's not fantastic, but it's not bad. If the school is covering your rent/key money, that definitely sweetens the deal. Key money is like 5 M won in
SK for a good apartment. Make sure this issue is cleared up before getting on the airplane.

It sounds like this job is a hogwan, the common after-school "cram-school" rich people send their kids to after normal school. These aren't bad IF you don't mind brats. I worked at one of these for about a week last year. The director lied to me about the ages of my learners and suckered me up there from Bangkok. He paid for that trip, but I had to pay for my return flight eight days later. It was an expensive lesson learning I hate teaching young kids. I should have punched the director out on the way out the door, though. I regret not doing that. F...ing liars.

Be warned, though. When I went to SK last year, I found prices outrageous where I was teaching. In Changwon, a government 'planned' city about 30 miles southwest of Busan, I saw 35-dollar pizzas, 12-dollar watermelons (medium-size), and ten-dollar tubes of toothpaste. Be careful with your expenses wherever you go.
