I hope this series isn't rushed or ends prematurely

I know this author said at one point that they thought the series would end after season two, however, I feel like there are still so many loose ends that we need to cover (and a hell of a lot of character development too). I know that the story has deviated from what they originally planned, hence why it's been extended upon, but I really hope they don't rush the series! Like there's still the learned sir and whatever he's plotting, then we have Jinhwa and Lord Min plotting some bullshit too, we need more context on Seungho's past and his family, and Seungho just needs linear character development without constantly recessing back. I just hope these all get resolved or at least touched-up upon before the series ends. (〜￣△￣)〜
