Review Detail of IamFallenAngel in From Extra to Main: Reincarnated 3 years before Novel timeline

I've evaluated my novel based on my criteria and personally felt the need to improve on certain points. Let's get to the point to clear some confusion regarding this novel. 1. This isn't an R18 novel, so please steer clear if that's what you're seeking. There may be some elements of romance, but it's minimal. 2. It's an enhanced version of 'Reincarnated in a Novel World,' so there will be similarities, but both the concept and stories will be distinct. 3. This novel has several plus points: two otherworldly characters, simulation travel, the talents of copying and creation, and a ruler of darkness. At the moment, I can't think of more than these. [Note: The novel introduces these advantages, but it won't solely revolve around them.] 4. I'll only map those characters who will appear for at least 50 chapters. Note: I'll revisit these points after reaching 100 chapters. [Author's Gift: Reason for leaving the previous novel: There were numerous shortcomings, as you might gather from genuine reviews. As compensation, I'll lock the chapters from the 101st chapter of this novel for four months.]
