Sumin and Suji. Suji studied Ethics. Both of them teach mathematics. Sumin lives in Mokpo (Seoul), and unusually, doesn't live with her parents. She's the Head teacher, and mercifully, has a wonderful sense of humor. These ladies have to go to work on Saturday to help prepare their students for a test on Sunday, which means, yup, they have to be at school on Sunday again. I finish work at 7:30pm most days, 8pm on Tuesdays and Thursdays. They have to stay behind and call parents for about another hour and a half. That's quite a lot of time to be stuck in one place. This why Sey left I think, the demands to stick around just got more and more. When the opportunity comes up for some lighthearted fun, given all their work, they really get into the swing of things.
