1 billion won if you survive a year in a burger shop.

There's a shower, a bed, and it's warm. But there's absolutely nothing around it. You must survive for one year strictly inside that burger shop. You can eat three, four, or five meals a day—it's up to you—but only burgers are served. However, the burgers are packed with tomatoes and lettuce, and the patties are premium Hanwoo beef, so the nutrition is sufficient. Going outside isn't strictly impossible, but as you can see, there's nothing to do but build a snowman nearby before rushing back in. Phones and computers are allowed. The internet is fast. The person making the burgers inside is Kurapika. He has a great personality, too.
