Will there be a Season 2

What do you think? When will be the season 2 released? I really enjoyed this series and I hope they wouldn't just leave all of us on a cliffhanger just like this. I can't figure out why the ratings are so low, it's DAEBAK show but still people aren't interested. I was definitely amazed by this series. I am not a fan of religious or cult including themed dramas but this one was on another level. Absolutely slayed it.
