His eyes and nose are sharp and distinct like his father's, while his lips are pretty and neat like his mother's. Like his father, he is tall for his age. Like both parents, he doesn't express emotions much, but he truly loves his family. As the eldest, he grew up receiving much love, and he is mature for his age, taking good care of his younger siblings. He listens to his father and mother well and gets along smoothly with friends at school. A truly exemplary son. He attends a private elementary school for children of wealthy families managed by the Black Wolf Gang. His mother and father take turns dropping him off and picking him up.

Second son of Nam Sahyuk and Cha Sunghyun. 5 years old. A mix of Sunghyun's genes with a touch of Sahyuk's sharpness. His eyes are pretty and clear like his mother's, and he has a cute, slightly rounded nose. His skin is white and fair like his mother's. His eyebrows are dark and sharp like his father's. Being five, he gets into mischief and has a lot of aegyo. He follows his older brother well because he takes such good care of him, and he really adores his younger sister. He attends a daycare center managed by the Black Wolf Gang. His mother and father take turns dropping him off and picking him up.

Third child and daughter of Nam Sahyuk and Cha Sunghyun. 100 days old. Despite being a baby, she is beautiful, having inherited only the best features from her parents. She has her mother's large, clear eye shape with her father's dark irises. She has her mother's distinct, pretty, and plump lip peaks, and her father's sharp nose tip. Her skin is white and clear like her mother's, making her red cheeks stand out. She is growing up under the overprotection of her mother, father, and two older brothers.
