Nah, That means this isn't going to end well right?

Most probably there is,  seeing how it all went down. In season 3 we might see the story of "OG spirit of mountain" and how he ended up going batshit crazy and took over Mooyoung's brother,,? and maybe Lee yeon's romance in that era ?. Can't wait!

Woah, I still didn't watch it...

Downlding, glad didn't read your reply completely 😅😎, otherwise, I might get spoiled 

that ending left out what happened to the original mountain god so im expecting season 3

After season 1, there were planned season 2 AND season 3. So, yes!

There has to be a season 3 because season 2 ended with a cliffhanger so...
