If I were to shorten it as much as possible, then I can only describe the story as "At first it was great, but then it got dumb" - Me(2023)
I was...baffled, it was good at first, but then after the 30th chapter you'd notice it got dragged out, and there was some weird points in the story as well, like the son of a bank's manager wanting to have a collab with the MC (but he obviously can't because MC doesn't even know him, plus he don't have the time to entertain others) so the dad come out and threaten the MC to do the collab or he will have his bank account frozen, then got an employee leaking his address, just for our MC changing his account to a different bank lmao, or how the MC just easily kill the golden dragon that was guarding a new dungeon (which the even the MC doesn't know about, and the dungeon was stupidly strong, except for MC not even the top adventurer at the time can go to the 1st floor) Bro came in at the last moment like a hero saving his princesses (+ a guy) then
swing-swing(ofc it got dragged out not just end with a couple sentences, but you know how it went) then the dragon is dead just like that.
The childhood friend situation as well, it got weird, like really weird, sure the childhood friend left him, said stupid shit like they are engaged when he's getting successful, but brother in Christ he knows it but just left it as is until she brought a whole bunch of people from the media to force him to agree that they are engaged (which they aren't), she even went as far to say "I'm pregnant", then the MC pulled out the "I have recorded our conversation back when you said rude shit then cut ties with me" card then left her there to get all the backlash. Later on she went to dungeon and made money by wearing revealing clothes, then weird shit happened and in the end she became a monster so the MC gotta defeat her, and you know this would have ended VERY differently, MC went "She cut ties with me, so I did the same, and whatever happen afterward is her fault" but if you think about it, MC has lived 10 years longer than her in the other world right? Where's her parents? Couldn't he just talk it out instead of wait and see? I don't know how the others feel but it left such a bad taste in my mouth, and fyi she's dead from chapter 52 and they still mentioned her name in chapter 184 as if she still has any relevant to the story at that point.
And even with MTL you can kinda pick up some of the bias from the author too, for example about how Japan has the most dungeons in the world, most of the top adventurers gathered there, and it's the top even in economic power (mostly thanks to MC)...so you say anywhere but Japan suck ass? The story is pretty self-insert as well when you look at it from a different angle, like how the MC has done absolutely nothing to get close to a girl and there we have 3 top beauties in his school flocking to him after he saved them
once (they fell for him at that time as well), having a male friend in his "harem" party (MC mostly acts alone btw) but it's totally okay since that friend already has a girlfriend, what a way to ensure MC got all the main girls. The antagonists are asses as well, most of them at the start are just "He will surely listen to me cuz I (somehow) have more authority" or "If I threaten him like this surely he will listen to me(somehow)" then we even have the "He has too much money, if we all demand him to share it (somehow) everyone will surely be happy", then we have the "Stupid noble trying to rape the main girl" shit as well, and surprise surprise, their plan worked, she was a step away before the MC came to the rescue...what? You are saying she's one of the top adventurer in the world with a stupidly high level and she still can't deal with the situation by herself?
I didn't bother to read anymore after reaching chapter 60 since I felt like there's no point, just skimp over some chapters that has interesting tittle and dang, I felt like I wasted my time since it became your typical OP isekai trash again. I myself don't have that high of a standard when it come to isekai mind you, even
The Isekai Returnee is Too OP for the Modern World with the same premises is more enjoyable to me than this...stupid fucking mess.
