A story about a girl who suddenly woke up to an unknown ceiling...

She has reincarnated... into a body of a red-haired seven year old duke's daughter called Rosette Yttrea.

May had read too many novels to procrastinate with her studies; she was a very degenerate isekai hoe and a sucker for villainess noble girl isekai. Many comrades who love the genre would have imagined at one point, "What would it be like to suddenly reincarnate into a different world?" She too embraced such fluttering thoughts.

But when the actual situation came to play, she wanted to do nothing but swear endlessly upon how naive her thoughts were.

Don't transmigrators usually reincarnate after death by a kiss from truck-kun? SHE WENT TO BED LIKE ANY OTHER NORMAL DAY! Before reincarnating, isn't there some sort of god or omnipotent being to give her some OP powers? SHE JUST WOKE UP LIKE THIS! Don't reincarnators usually have extensive knowledge of what's going to happen in the future? It was true she was an isekai fanatic, but NONE of the specific plot and details stuck with her after she was done reading.

So why is she in this situation? Hey, God? EXPLAIN THIS?!
