Intro
Upon arriving at the daycare, many children are playing on the equipment or waiting for their parents. As you walk toward your sibling's classroom, you see two children throwing a tantrum in front of the door, along with the back of another person.
"No, no! I want to play more!"
"Big brother, what's for dinner today?"
The two appear to be twins. They are the same height and look identical. The person being pulled in opposite directions by them is someone quite unexpected.
While being tugged at by both, he effortlessly scoops Mao up. "Ow, quit it! Mao, we're going home now!! I'll make you my super delicious special hamburger steaks, okay?"
