Honestly, I tried to sympathize with him and see where he's coming from too, really did, only to see the idiot sabotaging and making a fool of himself on a lot of occasions.

Can't keep making excuses for someone who goes out of their way to prove to the player why they
don't deserve any sympathy for being the way they are.
Yes, he is. He admits it himself, and his wife doubles down on it, if not through specific words, her actions and reactions in certain
fun situations sure don't leave a lot to speculation.
This fun fact is even specifically shown in the story, from the get-go no less, in case you forgot that closet scene in the beginning, first couple of renders in lol.
What's his excuse for THAT ?? C'mon man... some things can't be any more obvious than that, even his dick is small, as if that scene wasn't enough
incriminating evidence on him. His ass and lil pee-pee belong in cuck jail watching his wife provide entertainment for other guys while he (rage)
faps in appreciation to show his support for
all her
hard work.
There's an unwritten rule that says in Inceton's universe, if an MC doesn't pack the magical 10incher and there's competition for his LIs and side girls, it's over for him. Plus, the most obvious reason for why he's written to be such a loser and the story unfolds in a certain way is cuz the game's an FMC game heavily focused on the wife's naughty adventures, with a lil bit of action for the MC here and there, but that's it... she's the star of the show, not him. It's the spotlight for her and the cuck chair for him.
About that "stress" of his causing his
complete lack of desire for his wife... well, that's wrong and not a valid excuse for someone like this MC to make
every damn time he disappoints her or isn't in the mood to be intimate with her, unless he blames stress for having a 5inch pee-pee and almost no stamina in bed too.
Him not being able to
perform in bed like a male porn star after coming home from work stressed is understandable, but again,
barely ever wanting to have sex with his gorgeous young wife, and when he does, he does a piss-poor job at it, is something very weird and stupid, for some ppl a huge red flag too, more so since
HE is the one whining like a bitch the most about
her looking for comfort somewhere else.
It's practically common knowledge that a lawyer's job involves a lot of hard work, stress and time spent away from family, spouse in MC's case, which begs the question, except for the sweet, classic "plot" excuse, why would he get married so young and why would he be ok with his wife lazing around all day knowing his financial situation ??
Doesn't make any sense to me, most things and events in this type of games usually don't tho... it's why I said we shouldn't read
too much into it, sympathizing with an idiotic, useless MC with low self-esteem like this one should be out of the question, but that's just my personal view on this topic... don't have any problem if other fans disagree with me on it.
