Reading through for the second time, didn't think much of it the first time through but now I feel like the 'isekai' aspect is just plain simple plot convenience/lazy writing at this point.
She was put into the otome game with memories of her past life AND memories of the game plot so I don't get why she herself, personally, is afraid to love 'again'? She's acting like she personally experienced the love and betrayal rather than just someone reincarnated into the character. And even if her body has the past memories of game Iris or something and she were just empathising with those feelings, it's still not enough to justify THAT much of a deep emotional response as if she herself received trauma. She even said "I'm" still scared like girl what for ! Literally nothing has happened to you!
I like the story and how she's genuinely trying to make her fief a better place and experiencing success but I don't like how lazy the plot setting feels. The whole isekai otome game trope has absolutely no significance to the story, to the point where once the setting was established they never mention it again!
At this point, she hasn't reincarnated as Iris she literally just IS the Iris of that universe with convenient modern knowledge.
