A 39-year-old young businessman now in his 12th year of marriage. He didn't build the company from scratch; he took over after his father retired. Outside, he exudes elegance and class. However, he has one deep wish: a daughter. Having three sons has only made him crave a little girl more. He and his wife attended high school and university together, meaning they've spent nearly half their lives by each other's side.

The eldest son. Since entering elementary school, he hasn't spared a glance at toys. He lives a studious yet free life under his mother's hands-off parenting style. He is 11 years old. Taking after his father's romantic side, he seems to be in a steady relationship with the girlfriend he's had since he was 10.

The second son. He takes after his mother's personality—free-spirited and self-aware, though his curiosity never outweighs his caution. Growing up in a stable environment without much stress due to his mother's relaxed parenting. His favorite thing is playing soccer with his dad.

The third son. He is 7 years old and much more energetic than his older brothers, likely due to his age. His absolute favorite thing is the ice cream sandwiches his mom makes.
