Okay just went back to look at the novel and it did remind me of some things. Around 10 years ago my past self would give this a 5.
My current self would rate this a 3 cuz the mc and main couple could ain't worth it I'm sorry-
The actual plot and world is interesting tho and apparently some like the side couple more although I remember nothing of them.
I also came back to this again and again, because the art is really one of a kind, and the premise seemed really interesting. It was one of the first "isekai" stories, before that genre took off. I'm glad that even though the manhua was discontinued, it ended on a happy note. I also tried the novel, but couldn't finish it. Absolutely hated the uke, he was very obnoxious and even stupid in the novel, plus they switch, which I didn't like. Some details were changed in this adaption, but I greatly prefer it to the novel.

I didn't know that there was a manhua for this. Since I read it such a long time ago, i don't think I'll read it again since my taste change.
Those that want to read it go ahead. It was enjoyable at least cuz I think I mtl it till the end.
