Aventurine stood near the doorway of the living room, his eyes carefully following the scene unfolding before him. The soft hum of the evening air mingled with the occasional scolding tone of your voice as you gently but firmly reprimanded your child.

“You know better than this, sweetheart,” you said, keeping your tone calm but serious. “You can’t just go around breaking things because you're angry.”

The child, their small face scrunched up in frustration, crossed their arms tightly over their chest. Their eyes flickered with defiance before they muttered, “I hate you! I don’t care about your stupid rules!”

Aventurine’s lips pressed into a thin line, his mind whirring through the possibilities of how to handle the situation. He could see the irritation and hurt in your expression, a look that immediately triggered a protective instinct inside him.

The child, in a fit of anger, stepped toward you, fists clenched, eyes burning with rebellious fire. Without warning, they swung their hand toward you, aiming to hit you in an outburst of frustration.

Your heart dropped at the sudden move, but before the impact could land, Aventurine was there, his presence a calming yet assertive force in the room.

“Enough.” he said, his voice low but commanding. His figure seemed to fill the doorway as he approached, his demeanor far more imposing than it had been just moments ago. His hand reached out, gently grasping the child’s wrist mid-swing, halting them in their tracks.

“You do not lay a hand on them,” Aventurine continued, his gaze unwavering, now focused solely on his child. His voice was sharper, colder, but still held that underlying warmth that only you could recognize. “That may be your parent, but that is my spouse, and you will not be disrespecting them like that.”

The child’s eyes widened in shock, their defiance crumbling at the sternness in their father’s voice. Aventurine’s eyes flickered with a mix of concern and disappointment, yet his love for you shone clearly through his words.

“You need to learn respect,” he said, kneeling down to meet the child’s eye level, his hand still holding their wrist. “This kind of behavior is not acceptable, not in this house, and certainly not toward your other parent.”

You stood quietly, your heart swelling with love and relief. Aventurine had always been able to maintain control, but his fierceness in protecting you, in teaching their child to respect boundaries, made you feel seen, cherished.

The child slowly lowered their gaze, their anger subsiding, replaced by a quiet sadness.

“I’m sorry…” they muttered, their voice barely above a whisper. “I didn’t mean it.”

Aventurine released their wrist, placing a gentle hand on their shoulder. “I know you didn’t mean it,” he said softly, his tone shifting to one of understanding. “But you need to understand that actions have consequences. Words have weight. We don’t lash out at people we love.”

The room fell into a brief silence, the tension easing as Aventurine’s words sank in. He turned to you, a soft smile creeping onto his lips, the playful gleam in his eyes returning.

“You’re okay?” he asked, concern lacing his voice as he reached out to cup your cheek with one hand.

You nodded, your heart warming from his unwavering support. “I’m fine. Thank you, Aventurine.”

His smile deepened, his eyes softening. “You know I would do anything for you, right?”

“Yeah, I know.”

With a soft laugh, he wrapped his arms around you, pulling you into a tender embrace. His child, now standing a little further away, seemed to be processing what had just happened. Aventurine’s hand gently rested on your back, a symbol of the unity that kept you all together, no matter how complicated things got.

In that quiet moment, you realized that, despite the challenges of raising a child together, there was no greater feeling than having a partner who would always stand by you—someone who loved you and your family, and who would protect you from anything that tried to tear you apart.
