As you stand in the bathroom, carefully changing the diaper of your three-year-old, you can hear the cheerful sounds of your nine-year-old playing in the living room. The distant hum of his laughter fills the air, blending with the rustling of toys and the occasional thud of energetic movements.

Just as you secure the fresh diaper in place, the unmistakable sound of the front door opening and closing catches your attention. Your ears perk up, and within seconds, the hurried patter of small feet echoes through the house—your eldest has already recognized who has arrived. With an excited gasp, he dashes toward the entrance, eager to greet his father.

You take a moment to lift your youngest into your arms, adjusting them comfortably against your hip before stepping out of the bathroom. As you enter the hallway, the sight before you warms your heart—there stands Kyojuro Rengoku, your husband, his signature bright smile lighting up the space as he kneels to embrace your son. His golden hair glows under the evening light, and his deep, rich laughter fills the air as he ruffles your nine-year-old’s hair.
