Specifically, MC is a pharmacist, raised in a village of former heroes, so his standards for everything are those heroes, leading to wacky results when he finally ventures out into the world outside and starts interacting with normal people. Cue laugh track. Sure, all he knows is heroes, fine, but you would think that after spending a certain amount of time outside and being CONSTANTLY EXPLICITLY TOLD DIRECTLY TO HIS FACE that his standards were way too abnormal, he might, maybe not fully accept it at first, but at least start to suspect that maybe he's the odd one out. Of course, even if he knew that his standards were out of wack, he might tone it down a bit with the stuff that has already been brought to his attention but anything that hadn't been specifically addressed yet, he wouldn't know other people found it weird, so you'd still have nearly unlimited comedic material to showcase how out of touch he is with normal people just by having him frequently pull out something new to dazzle his surroundings with... wrong, you replay the same old gag over and over again without the MC ever stopping to consider his actions or learning anything, occasionally slipping in something new so things don't get too stale. Don't stop beating that horse, it ain't dead yet if it's still twitching. So if the MC never learns that his actions are crazy and abnormal, surely at least the supporting cast will eventually get tired of overreacting to his shenanigans, right? No, of course not. Even with the same crazy thing he has repeated dozens of times, they still freak the hell out each and every time he does it, let alone whenever he rarely does something new.

The running gag I keep referring to is that the MC can extremely easily and with very little cost produce legendary elixirs that can cure all wounds and status defects with no side effects whatsoever. Because of this, so-called "legendary elixirs" hold very little value to him so he readily dirstributes them for even minor things like a minor headache. Obviously this is a legendary potion so the people around him freak the hell out EVERY. TIME. HE. DOES. THIS. He never learns that this is weird, they never get used to it and stop losing their mind over it. Cue laugh track. Then, occasionally he will run into a problem that can't be solved by throwing elixir at it, but that's fine. Whenever this happens, my guy turns into f*cking Doraemon with his interdimensional pouch of hyper-specific fixes for anything and everything. Lady caught a super rare incurable disease, but actually she's being poisoned by something even more obscure and less curable? Well my guy actually knows the cure. Oops! He accidentally punched a guy through a supposedly unbreakable wall when sparring (did I mention our pharmacist is also a combat genius?) ! Don't worry, he'll just whip up a repair potion real quick. Oh, this divine beast has brain cancer, let's just use a freaking cancer reversal potion on it, and then because it is upset that it grew too big to return to its friend in the city, we'll have it chug a transformation potion and turn into a hot woman. Harem member get+! Oh no! Someone literally died. Like, actually properly stopped living and all the way died, but that's fine. Say it with me, class; revival potion.

Now, if one of MC's potions isn't for a situation that's too specific (like cancer), there's a chance that that potion might make an appearance again later, but whenever this happens, the side characters seem to develop selective amnesia and forget about its existence entirely so they can do the reaction with all the same intensity as the first time they saw it. Especially the revival potion becomes a fan favorite. Bro literally uses the revival potion on a character, and then later that same character acts as if they've never heard of reviving the dead when he uses it again on someone else. It's important to note, they weren't just freaking out because the miracle of resurrection is insane even if you already know about it beforehand, they seemed to genuinely be upset that a character was dead after they already experienced death and revival themselves, and then shocked when the revival potion got used.

Throughout all this, MC remains almost sarcastically humble. Despite his actual god powers, he doesn't consider them a big deal because he was raised in a village of heroes where casual revival of the dead was par for the course and hunting down natural disaster-level legendary beasts was all in a day's work. That's fine, but after he leaves the village and begins interacting with normal people, he still maintains this mindset of "well, anyone can do this" with all the crazy OP stuff he does. When it turns out that, actually no the f*ck they can not do it, he doesn't look down on people as being weak or unskilled, or think that maybe he's actually kinda amazing, he just kinda... ignores it, I guess? If he acknowledged that he's able to do things that not only can the people around him not do, but that they consider to be legendary feats, it wouldn't make sense to keep his humble, practically self-deprecating attitude, so he just kinda doesn't acknowledge that he's doing anything out of the ordinary even when people are actively screaming in his face how ridiculous it is that he's able to do what he's doing. Cue laugh track. Even when he does something his master, someone he views as being at the pinnacle of medicine, couldn't do, he determines that he "still has a long way to go." Like, it's good to not get conceited, but it's not conceit to merely acknowledge the fact that, even if it's only one thing, you made something your master was not able to so even if you're not quite on his level yet, you're definitely catching up.
