Aizono Moe's, let's call it unique personality, wasn't unrelated to her family background.
Now, don't get the wrong idea—her family wasn't complicated or dysfunctional. On the contrary, the Aizono household was about as typical Japanese as you could get.
Most families in Japan run on a single-income model. In a three-person household, the wife stays home with the kid while the sole financial burden falls on the husband's shoulders. So once Japanese women get married, they tend to become fiercely loyal to their families—especially obedient to their husbands. Their own families expect nothing less.
In their mindset, serving men and serving the family becomes second nature. That's where the idealized traditional female image of the Yamato Nadeshiko comes from—the perfect, graceful, submissive Japanese woman.
Aizono Moe's mother was exactly that kind of traditional Japanese wife. In daily life, she placed enormous importance on proper etiquette toward her husband. She'd change his shoes, adjust his clothes, tie his tie when he came home. She'd personally greet him at the door when he left or returned, bowing and seeing him off like a scene straight out of a period drama.
She respected her husband immensely—both in public and behind closed doors—and did her absolute best to fulfill his every request. Obedient as a well-trained lamb.
In Aizono Moe's memory, her mother kept the house spotless every single day, never once asking her father for help, never complaining about anything. She never raised her voice, always spoke in that gentle, soft tone, and was always so affectionate with her father.
Conservative. Rule-abiding. With only her husband in her heart—kids came second. She did her part and never meddled in anyone else's business. Stayed home all day with her husband, devoted herself entirely to him.
She basically checked every box on the patriarchal wishlist. As long as her husband was happy, she was happy.
This was the "perfect wife" that most Japanese men dreamed of having, and the "model mother" that many children looked up to.
Aizono Moe was heavily influenced by such a mother, which made her own personality more introverted… but she knew something that most people didn't. Her mother had another side—a lesser-known, hidden side.
That side came out at night.
At night, her mother would become incredibly alluring and open. To put it bluntly… really perverted.
When Aizono Moe was little, she'd wake up at night to use the bathroom and hear shouting coming from her parents' room. She thought her mother was being bullied by her father.
As she grew older and gained more life experience, she realized the truth: her mother wasn't being bullied. Rather, her mother was asking her father to bully her. Her mother liked being thoroughly dominated by her father.
Now, that might sound a bit strange to outside ears, but a "rich and frequent nightlife" between husband and wife was actually the key factor preventing internal conflicts in the Aizono household. Go figure.
See, traditional Japanese women are incredibly tolerant of their husbands. No matter how badly he treats her—even domestic violence or cheating—she'll first assume it's her fault. "I must have done something wrong to make him stray…"
They don't easily give up on the marriage. Instead, they try to change themselves to better accommodate their husbands, all just to keep them by their side.
They don't even care if their husbands seek other women. Having a mistress? Elsewhere, that's practically unforgivable. But Japanese women can tolerate that much from their husbands.
This isn't just because Japanese women have no independent income, leading to low status in the family. It's also because the idea of patriarchy and male superiority is deeply, culturally ingrained.
But such a mindset is actually a "demand" imposed on them by society at large.
Just like the old Confucian "Three Obediences and Four Virtues," it's a form of social domestication—or to put it in modern terms, "common sense modification" enforced by the world around them.
However, this learned domestication leads to severe mental suppression for most housewives. Not everyone can be a Yamato Nadeshiko-style super wife and wise mother for their entire lives. They tolerate their husbands and children, but no one tolerates them.
This is also why Japan has one of the highest infidelity rates in the world.
The probability of extramarital affairs is especially high, because when men are out working and not at home, women who stay home feeling unsatisfied are very likely to fall in love with someone else and cheat on their husbands…
Which, coincidentally, is why the Netorare (NTR) genre has remained evergreen in Japan, consistently dominating the doujinshi world by a massive margin year after year.
Truly, art imitates life.
Fortunately, the Aizono family was very harmonious, and Aizono Moe's mother had no reason to cheat on her husband. Their relationship seemed genuinely loving, night and day.
Aizono Moe herself had received the most traditional Yamato Nadeshiko-style education. But later, during her art studies—in order to understand the human body for her drawings—she ended up accumulating a lot of extracurricular knowledge that most proper young ladies probably shouldn't have.
So when she called Kuroha Akira "Master" in her heart earlier, it was actually no different from how traditional Japanese women subconsciously obey their "husbands." She just hadn't realized it herself yet.
Even though she had already mentally submitted to Kuroha Akira, her emotional density prevented her from recognizing the romantic feelings that were quietly budding inside her.
Kuroha Akira, for his part, found Aizono Moe very obedient and easy to direct. So he continued.
"But don't worry. I won't tell anyone about your color weakness. However, Moe-chan, from now on, you have to color according to my instructions. Got it?"
"Yes! Oh, um… Kuroha-kun, your arm just touched my… mmm… I'm sorry! I dirtied your arm…"
Even though she herself was in a much worse state, she was still more concerned about the spot where Kuroha Akira had touched her.
"It doesn't matter. I'm not a germaphobe. Getting a little on me isn't going to make me sick."
Then, completely out of nowhere, Kuroha Akira asked a very strange question.
"Speaking of which, what color did your own pee on the floor look like to you just now?"
"Mmm… light beige, I think…"
"And the nosebleed?"
"Dark purple."
Light yellow → light beige.
Dark red → dark purple.
That confirmed it—she had red-green color deficiency. The world in her eyes was probably similar to having a grayscale filter slapped on everything.
"I see. Actually, your urine is light yellow, which means you didn't drink enough water today."
Urine gets darker yellow when it's concentrated. The longer you hold it, the yellower it gets.
"So here's the deal, Moe-chan. Remember to drink more water normally. And don't hold it in—holding it too long is bad for your health. From now on, go to the restroom as soon as you feel the urge. Understood?"
"Yes… I understand… I'll remember it firmly!"
Kuroha Akira deliberately used this lecturing tone to ease her embarrassment about the whole earlier incident.
But to Aizono Moe, this was a brand new "order" that she needed to execute.
She had now become Kuroha Akira's mindless supporter.
Whatever he said was right.
And she had to obey it without question.
