I remember I used to think this was some kind of Lolicon stuff when Instagram showed me a Tappytoon advertisement but I am seriously so happy that it turned out to be different.

Story: 9/10
The story plot isn't exactly a new one but nevertheless, I enjoy it greatly as I am a fan of Isekai plots. Furthermore, you never know what happens and the interplay of the different characters adds more to the suspense.
Moreover, I also like the fact that romance is not in the spotlight of this story.

Art: 10/10
I would even give an 11 if it was possible. I find these images so beautiful, I really really love the appearances of the characters. The clothing is very detailed, much to my pleasure. And oh my God, the royal bloodline's jewel eyes hit differently. These are just out of the world. If they were real, I would probably think I died and landed in heaven somehow.
The appearances are what made me read this series in the first place. I even read some parts repeatedly, just to savour the drawings with my eyes.

Characters: 9/10
The characters are great!
Each character has a meaning and therefore none of them feels as if they're not needed for the story.
I am especially enamoured by Claude, Lucas and Felix. Those are my men.
I also like Athy very much; the girl is too adorable for her own good.

Enjoyment: 10/10
Obsession. Maybe that's what I feel with this manhwa.
As I started reading this, I did not expect that I would read the whole season 1 (chapter 1-46) in one night; I literally absorbed this until I caught up to the current chapter back then.
Now I am patiently waiting for new chapters.
There was a Christmas break (2019) and I suffered so much because every chapter feels like a cliffhanger to me..

Overall:
If you like Isekai, Fantasy and Shoujo - this is the manhwa to go.
I highly recommend it.
