[Season 1]
⠀⠀⠀Author didn't even try to properly represent a blind person. If it wasn't mentioned in the narrative and we weren't shown the walking cane, we wouldn't even know that he's blind. He follows objects with his pupils, holds eye contact with people he's talking to and easily performs actions that would be difficult for someone with his disability. And after he got isekai'd, he doesn't have to transition as if he was sighted his whole life, his past blindness was only ever used as an excuse for others to pity him, and was otherwise pretty irrelevant. And of course he can't even pretend to be blind after returning home. Good thing other characters are too stupid to catch on.
⠀⠀⠀To say that this novel has an 'Oblivion NPC'-tier dialogues would be an insult to Oblivion. The writing is dreadful. People do not talk like sentient living creatures, it's not even on the level of Zuckerberg human imitation, but much worse. Not only does everyone talk like robots, but also do so in broken English, so translation's not good.
⠀⠀⠀Why is a witcher medallion, sold by some random woman on the street, teleporting our protagonist to a fantasy world? Why does he summarize in all the detail what literally just happened? Gets thrown in jail for three weeks because "we don't trust you" and "want to study the medallion". Oops sorry we destroyed your medallion, but we'll surely figure out how to return you to your world, because we've got nothing better to do. Until then, you're free to go wherever and do whatever because what could go wrong, right? We also burned your clothes, btw, AND you have to pay for new ones, so I guess you're now our bitch and have to pay the debts. MC be like: "sounds perfectly reasonable, have a nice day". He later need to get into the tower, but it's guarded, and by chance he learns that the guardian is afraid of animals. So he brought a pig with him and she LITERALLY drops unconscious like a sack of potatoes. A goblin holds a cat hostage and is willing to trade it for an extremely rare fish. So instead of asking villagers to help kick his ass, our MC goes fishing and actually catches the fish, because it's super rare, so it makes sense, right? Why is everyone going out of their way to help the MC? He's done nothing of equal value for them and is a literal stranger, so this kind of compassion and comradery is unwarranted. The reason behind MC pretending to still be blind in his original world is so retarded: "you wouldn't be able to explain", well how about he DOESN'T HAVE TO?? He could say that it just happened and he's no idea why, and nobody would be any wiser, or are you trying to tell me that they would eventually suspect parallel worlds and inter-dimensional travel, because some blind boy could finally see? There are also loads of porn logic like brewing a semen potion with penis flower to restore magical abilities.
⠀⠀⠀MC is an autistic wimp. If you're blind, that doesn't mean that you also have to be sobby, socially awkward imbecile with no backbone and no self-respect. Yet for some reason everybody's crazy in love with him. Like at first he's a "filthy human scum", 5 minutes later he's already "kinda cute doe", 2 days later he's "the love of my life, I can't live without him". Making puppy eyes, telling his sob story or simply showing his dick is usually more than enough to conquer any wench for this protagonist. He says a couple of compliments and already gets a status of best guy in the world, this level of affection is simply not deserved.
⠀⠀⠀Sex scenes: a decent animation shown from 3-4 angles over a dozen of times. Naughty talk is bland and awkward, sometimes there is NO sex dialogue at all, not even onomatopoeia, just humping in complete silence. There is music with vocals that doesn't really fit the mood, no sfx, no clapping, no moans. Almost no teasing or build up either, sex just kinda happens. Most girls are very attractive, tho there are a couple of freaky-looking sidekicks.
Conclusion: definitely a bad read. Maybe a decent porn, if you skip a lot of text?
