I wonder if the 2 reincarnators will realize the inconsistencies started with Luciana managed to hire a new maid.
But before that, they have a bigger problem. If they don't wake up soon, the prince's servants are gonna walked in the room next morning and saw the 2 of them spent the night in the same room.
The first divergence is actually since the beginning when Melody took the public carriage.
Because that allow her, the heroine, to arrive at the capital without being escorted by the knights.
(and as mentioned back then, the public transit was a project start by the crown prince i.e. these two)
Also as much as things have diverged, key events are still playing out but with the roles filled by someone.
Melody did run into the prince.
Luciana being escorted by what'shisface fit with a story event.
Demon king did attack.
Im actually really loving this story, and normally I get annoyed with side characters like the other 2 reincarnates, but I love these 2. Looking forward to future chapters a lot.
