This manga has amazing start, after 300-400 chapters things get complicated and from 10-20 witches that we know names, it suddenly becomes like 100 and everyone gets forgotten, main story is lost and now things are just getting complicated and manga is becoming like other manhuas with hundreds of chapters that lead to nowhere. Art has dropped significantly and main romance is simply weird. It says harem but he picked 1 girl to marry (anna) and there is still lingering romance with 2nd fml (nightingale). It had a promising future and then it fell apart. Instead on focusing everything on battle for the kingdom and then becoming a king, he is literally still a guy who runs his town given by his dad (previous king) and where is the rest of the kingdom? Nothing was said about it. And demons are all of sudden a neighbours with his city as usual. Random expeditions with new lands also makes no sense. Long story short, read it halfway and drop it when you're the most satisfied. Don't pursue to read it whole.
