Unfortunately the house was always a side character, so it makes sense they completely dropped what she's capable.
Objectively wrong, men can help themselves, cheating happens because tthey're pathetically weak or scumbags, we're not animals, if you cheat it's because you chose to cheat.
Seriously dude, as a man I have to tell you, have some fucking self-respect and dignity, the notion that man can't help themselves is nothing but pure nonsense to excuse cheating, if a man cheats that's 100% on him, if you do it that's on you.
Also nonsense, laughably even, since most cheating is out of opportunity, normally from worthless man, they either go out of their way to purposely cheat simply because they can or the opportunity showed up and they decided to go with it.
My dude, with the way you keep justifying cheating I honestly pity any women who decides to marry you.
The funny thing about being human? Free will, we can think and choose what we want to do, we're not animals that act exclusively on instinct, if you really think you're no better than an animal then go live in the wild like one.
And before you even think about it, don't even bother replying if you're gonna make more excuses, I've heard all of them before and they're all pathetically weak and worthless, none even slightly convincing unless you're planning to justify your own future cheating.
Or he has self respect, dignity and is a loving husband, like a man should actually be instead of a child with poor impulse cohtrol.
It won't happen because he was never portrayed as having interest in anyone else, some people love and respect their wife enough to not cheat on her, shocking I know, oh wait, no, not shocking, because that's the expected when you love someone.
Edit: sorry if I was a little harsh, but really dude, men not being able to control themselves is nothing but pure nonsense
She's his wife for all intents and purposes and the first real figure in his life,making her grow with him should've been the logical path,and they did to an extent.
Does make me wonder if it was a pivot away from a more overall suggestive,if not erotic,theme due to a change from the novels' sales or feedback,maybe even an editor...
People love talking about how humans aren't animals...just because we're the most dominate and one of the the most intelligent beings on this space rock whose surface is 97% covered in
dihydrogen monoxide does not nor ever mean we are not animals.
It should be noted inteligence is directly correlated to how "animalistic" one can be,chimpanzees are so sexually free that they get it on with each other regardless of who,whilst dolphins are the rapists of all time whilst absolutely enjoying the act of sending porpoises above water for that gravity assisted whallop.
Then comes the humans,whose fairly shorter history is chock full of all the bloody things we've done to each other and the world itself,to the point we might not even be here several generations down the line,all for a myriad of purposes we have so neatly put into a hierachy of needs n' wants.
Why do we choose to do things,even if the choice isn't a logically sound and beneficial choice overrall compared to what we could be doing instead?,because we are animals.
Why sleep when you can finish off that task and sleep at a nice sleep schedule?
Because the animal in you felt like it,and you'll be happier now(followed by being unhappy later when the task nears its' deadline and you pull several all nighters).
Why eat when you can travel for some time and get a healthier alternative?
Because the animal in you felt like it,and you'll be happier now(followed by being unhappy later when the weight gain causes health issues).
Why pound that single and easy chick/studmuffin when you can wait and get it on with your wife/husband?
Because the animal in you felt like it,and you'll be happier now(followed by being unhappy later when the wife/husband finds out after the chick/studmuffin wants more commitment).
Why stab that neighbour when you can just talk them out of using their leafblower at three in the morning during the weakends?
Because the animal in you felt like it,and you'll be happier now(followed by being unhappy later when the police find you peacefully asleep in the blood soaked sheets with the neighbours' head impaled on the leafblower
What one feels like doing is what the animal within wants,and it needs but just a moment,a lapse,the lowering of guard,the mental darkness,an impulsive thought,for it to occur.
But it also happens are the strain reaches too far,after the monotony erodes any ability to care,as the lack of any satisfaction swells to burst,the self loathing reaches a tipping point,and it this state,the animal within points to the easy and more evil choice within grasp.
The angel on your shoulder can only watch your human self fall into despair as the devil makes a very compelling argument to the animal.
So yes,men and women,young or old,mature or immature,just can't help it,they desire,they want the things they can't have and will take what they can get for only so long,it is because to err is to be human,and only the divine can trully forgive the animals below.
No amount of willpower can stop it,only suppress it when it builds up with no outlet,that is why we put all these social barriers,these rules and laws,these comandments,but also make all these sports,games,entertainment media,social gatherings and the like,all to meet those needs from the stone base to the golden top of those pyramids.
Willpower itself is a grain in nature,it's easy to put effort into overcoming a challenge when the start and end journays towards what you want.
But even simple tasks are a chore when you simply do not want them,going against the grain despite being shorter then the route along it.
This is compounded when one realises the path along the grain is more often shorter,the happiness being right there,even if it is just temporary,even after putting it off stubbornly and doggedly to go against the grain for that permanent reward,one look with tired eyes is all it takes to think the grass is greener,even as it gets blown away by the wind.
So yes,it is exactly as you say,they chose it,their low willpower,their cowardice,the oppurtunity was there,the temporary happiness,the ease of relief,because they can't help it,their inner animal told them to when it had the chance.
When it then comes to the specifics,men want quantity whilst woman quality.
So if the man gets a quantity that is lacking,seeking other sources becomes more compelling,and if the woman always feels lacking regardless how often,other sources might be the key to better quality.
Of course,too much of a good thing always persists,men who get so much quantity will find no more challenge,might even gain confidence to try and pursue others as part of that prideful ego borne from easy conquest,woman who get that quality will always want it even as the monotony of it all erodes what the origial source has,only for a replacement to suddenly present itself.
There's a reason rats being hardy in tough conditions can be detrimental when the harshness is gone,albeit,that's a societal level tangent about the drive to survive.
This isn't about right or wrong,nor if forgiveness should be given,nor if they should be punished,nor if they can justify their actions,this merely what it is to be human,who are just animals who wish for better but retain the same old.
All this is also in regards to normal people,the people who do feel the weight of the animal wihtin after listening to it,we haven't even talk about the empathy lacking psychos who embrace the inner animal to feel satisfaction not from the benefits of helping another member of their species through mutual animalism,but to see that fellow struggle to even match a fraction of their power.
They want to feel in control of another who offers themselves,they want to see the pitiful naive attempts of their spouses to keep them,the society who thinks them as normal as they smirk about their secrets,they do it simply because they can and their inner animal roams free,the dopamine flowing in as they go from one hopeful to another with any care.
So this then brings us back to our chad man Daichi,who fills his needs with golem fun times,a literal saint who hasn't even done anything for/with his house after getting it on like Donkey Kong once,since the plot may lack accuracy with a single shot but maintains a consistency that can't really be proven nor denied with a single shot,the lack of house growth nor other abilities,just taking day by day to serve as a the non-human wife that she is,Daichi has the willpower,the self control,the suppression of his human desire brought about by the inner animal,to not get laid anymore despite the options of others,many of whom who care for him quite deeply,options that his house probably won't mind beyond simply being a safeguard against making things even taller,this is how less human nor animal but more God like Daichi is.
He is expected to not just love his wife,but to make love to his wife.
Worldly desires be damned as he fulfills them with creation.
My fellow comrade who reads this,search your feelings,you know it to be true,the animal can tell you as much before you suppress it once more so you can continue to fit into the limits society has placed for the pursuit of collective happiness,and accept that one day,a mode might spring forth,one that may not be within the realm of betraying feelings set by traditional expectations,but a mode that can be attributed to a mythical creature who now represents just being true to oneself,the failure of a creature who endures on.
The mode of a goblin.
