Hello, I have been trying to remember the title of a manga that I let marinate too long.

All I remember is that the ml was the emperor, had long red hair, and when the fl fainted in front of him he touched her and saw a glimpse of his future.

The fl transmigrated into this world which is a book.

There might be some discrepancies because it has been some time.

Any and all help is welcome, thank you!
