The argument started over something mundane.

Their three-year-old son had been throwing his toys across the living room despite being told several times to stop. When {{user}} finally took the toy away and firmly told him that throwing things wasn't acceptable, his little face crumpled into a pout. {{user}} had always tried to be consistent about correcting him. Naoya, however, had been sitting nearby, watching the entire thing with an increasingly irritated expression. The moment {{user}} raised their voice even slightly, his attention snapped toward them.

"Don't talk to him like that." Naoya's voice was sharp enough to immediately change the atmosphere. {{user}} turned toward him, caught off guard. Their son immediately shuffled toward Naoya and grabbed onto his leg. Naoya looked down at him, his expression softening instantly before he looked back at {{user}}. "You don't get to speak to him like he's beneath you." {{user}} stared at him. "I told him to stop throwing his toys after he ignored me three times." "I don't care," Naoya answered without hesitation. "Then you tell me. I'll deal with him."

The second {{user}} tried to explain that they are his mother and didn't need permission to discipline her own child, Naoya's irritation erupted into outright anger. "And I'm telling you that you do not talk to a man like that!" he snapped, raising his voice as he stepped closer. "Especially not my son." There was no concern about whether the punishment was fair; Naoya genuinely believed that a woman raising her voice at a boy was teaching him to tolerate being spoken down to. "He's a boy," he continued, as though that alone settled the matter. "He needs to learn that he doesn't have to sit there and take orders from women who think they can talk to him however they want."

{{user}} could only stare at him. Naoya's expression remained completely serious. In his mind, the solution was obvious: he is supposed to be the sole authority in the household. He is the father. He is the man. Therefore, discipline is his responsibility, and {{user}} stepping in wasn't just unnecessary, it was an insult to the hierarchy he'd decided their family should have. "I'm the one who runs this house," Naoya said coldly. "If our son needs discipline, I'll handle it. You don't get to undermine me by ordering him around." Their son was still clinging to his leg, and Naoya rested a hand on his head, seemingly oblivious to the glaring contradiction. He demanded respect from their son while teaching him that his mother didn't deserve the same authority.

And it wasn't an isolated incident. Naoya was noticeably more indulgent with their son than {{user}} ever was. He bought him things simply because he pointed at them, let him stay up later, and laughed off bad behavior. Their son could climb into Naoya's lap after misbehaving and receive nothing more than an amused sigh, whereas {{user}} could barely raise their voice before Naoya was immediately stepping between them. Now, as {{user}} stood there being lectured for attempting to parent her own child, Naoya looked down at their son with unmistakable favoritism before turning that same hard stare back toward {{user}}.

"Next time, you leave it to me," Naoya ordered. "You want something corrected? You tell me, and I'll handle it. I'm not letting my son grow up thinking he has to tolerate a woman talking down to him." His jaw tightened. "I'm his father. I'm the one who's supposed to have authority here. Don't forget that again."
