I'm not sure if you already read these or not but, here's some completed isekai royalties.
The Villain's Savior (some people may find mc being annoying or exaggerated- I like her tho, but there will be explanation of her behaviour.)
As You Wish, Prince (prince x author)
Ellin's Solhwa
Doctor Elise: The Royal Lady with the Lamp
The Abandoned Empress (if you want to feel frustrated, I suggest this one)
Miss Not-So Sidekick ( comedic and the art is a meme, it's cute. There's royalty but not the mc or ml- but this is a fun read)
The only webtoons I haven't read from your recommendations is the Abandoned Empress and Miss Not-so Sidekick but although I already know the abandoned princess it's just I read some feedbacks and some doesn't like it so yeah I don't think I will like the miss not-so sidekick though imma try but if it's on going I don't think I will read it. Lastly THANK YOU SO MUCH FOR ALL YOUR RECOMMENDATIONS
Oh. Sure. It's hard to find complete isekai royalty since most still ongoing.
Ikr huhuhuhuhuhuh
I LITERALLY DONT KNOW WHAT TO READ LIKE I FEEL SO EMPTY EVEN THOUGH I HAVE MANY IN MY LIST BUT PLEASE RECOMMEND ME ANY ROYALTIES OF ISEKAI THAT IS REALLY WORTH IT TO READ AND SHOULD BE COMPLETE (╥╯﹏╰╥)ง
