You are correct, I dislike shoujo but this one is quite interesting.
Yeah, that's cause it doesn't follow the tropes AT ALL. Which kinda makes it non-shoujo for me, so I don't count it as one. WHICH IS WHY I LOVE IT. I don't know about Empress of Another World, but I'd say Doctor Elise is on the same level when it comes to the story.
I'm still waiting for that one main obstacle for Elise in Doctor Elise. One that would make her two-dimensional and for her bad past attitude to still impact the life she's trying to correct. She seems too perfect at this point of time and no one out there is really questioning her actions or her quite impossible medical skills (for a sixteen year old!). Good thing she has this backstory as a "cornerstone" for her character. Something's up but it's not there yet. I'll wait.
Of all the lady-protagonist-goes-to-another-dimension webtoons I have started to read (Doctor Elise, Empress of Another World), this by far is the better-paced, better-written and most intriguing one. Even shoujo-dislikers would probably like this one.
