MC talks about Sword Master being every male fantasy novel reader's romance but, he doesn't actually do anything to become one, other than following the original body's routine of training for 3 hours mindlessly, I mean sure he wasn't some kind of genius before getting transmigrated but that shouldn't be stopping him from seeking proper teaching for it. But I guess that could get resolved as he has enrolled in the academy and their instructor seems to know how to properly teach.

The world setting has mana and magic and MC says he could feel mana when he practiced with the sword but didn't elaborate any further nor did he think about how to become more skilled at it.

Since, MC was an avid fantasy novel reader on earth he must have read many novels including the Sword experts, masters, grandmaster, transcendents and more such characters, so why he isn't applying any of that so far, I don't really understand.

Then there's that auto correction going about that we can also define as the will of the novel world or something but the MC is just thinking about how strange it is instead of actually doing anything to understand it's whys and hows, that he should be able to if he just opts for a magic class too and takes it seriously. I mean come on if magic exists, no matter how glossed over and unremarkable it seems from what has been shown to us so far, there must also be mind control and domination spells out there! Why isn't he linking this auto correct phenomenon to something related to magic?

Then there's that harem tag in novel description when the MC clearly seems to be hell bent on marrying his fiancé. If the author ruins this novel just to add more girls in a relationship with MC who prefers monogamy then this isn't going to be my cup of tea even though I don't dislike harem.

I also don't understand the character of Lily the OG Female protagonist of this RoFan. From what has been shown so far, it seems she got transmigrated in this world far before the MC and was even thinking of not getting involved in the original plot line. But then she experiences the auto correct function and does a 180 in character, then just as she is done ensnaring the prince, she meets someone who might be a transmigrator like her, and now she wants to befriend that someone because she feels lonely for being thrown into this fantasy world. And reason for her volatility is given as her wanting to go back to earth. I mean girl if you want to go back so badly, instead of playing house and academy intrigue, you should be burying yourself in magic study and whatnot to rip open a portal to earth and go home.

Maybe, because it is still early and I have read only 15 chapters of this but if these plot holes so far are properly explained and filled out moving forward then this could be good story.
