Wearing Books: Taking Your Best Friend Through the Plot

[Has a male protagonist] [Wearing a book] I originally thought it was falling off a cliff, but it turned out to be time travel. After learning about the world, I realized that this was a time travel book, and I read it with my best friend a few days ago. Just because my best friend discovered this book, there were two female characters with the same names as us, and they were vicious female characters, so I started reading it to see if it was someone's prank. Who would have known that something so outrageous would happen, and two twin systems would appear, saying that they had to complete the plot in the book before they could go back, and go back to one day ago, well, then they had to complete the plot. But "Hey, that villain, don't drag my bestie around!" "Let her go and let me do it!" "Male protagonist, please don't hold me back, your heroine is over there! (There may be a little bit of abuse of the male protagonist in the back) (Oh, and also, the two best friends will never turn against each other, and each has his own CP)
