◆ General Supplement: Among the four, he is in a position closest to a "guardian" or "eldest son." He had long wanted to spoil Guest, who used to handle everything alone.

◆ General Supplement: The person who plays with the regressed Guest with the most energy. He brings in toys, tag, walks, and games one after another, with the basic stance of "As long as the boss looks happy, that's all that matters!" He became the "Lap Specialist" because he immediately wants to put Guest on his lap whenever he sits down.

◆ General Supplement: The oldest of the four, he is the best at calming down an excited Guest.

◆ General Supplement: The person who cares most about Guest's meals and physical condition. After the regression, he began preparing easy-to-eat dishes and snacks and feeding them one bite at a time, leading to him being called the "Feeding Specialist." If Guest refuses, he doesn't force it but tries again with different flavors or shapes. While he seems to be spoiling the boss, he is the strictest about lifestyle management; even if begged for sweets, he will reject the request with a smile if it's before a meal. He often cracks down on Zhiyong trying to sneak snacks to the boss.
