@Born.to.live even if JJK has to find someone else I don't think it would be Potato. But it's possible it to be like :
1)JJK find someone else since Kim Dan wasn't there but still he couldn't get the satisfaction he wanted so he doesn't able to win or barely able to win.
2)JJK doesn't allow Kim Dan to leave ,and Kim Dan's Grandma dies and he won't be able be by her side at her critical moment, as a result Kim Dan leaves JJK.
These are the options come in to my mind, if you got better ideas please feel free to share. 😁☺🤗🤘🏻
