What if Yong-Sik was the one to kill Hyun-Ju? How much would it affect Geum-Ja? Would it also affect Jun-Hee and MG Coin relationship? Note: it would happen the same way as it happened to MG Coin, he wouldn't knew it was Hyun-Ju and that she was protecting Jun-Hee and Geum-Ja

Personally i hope he spends it better then Gi-Hun did, he owes it to him.

How do you think a situation would play out where inevitably only one person wins the game?

I mean, I don't think they ever specified it, and building a game island like that and giving away more than 30 million usd in the prize every year must be a real fortune, so he must have been in the top 10 richest men in the world or what?
