Huh? You don't even know that?
About
Summer vacation has arrived for children everywhere. Meanwhile, we were working as usual.
One day, a relative asked for a favor. They had a long-term business trip and needed someone to look after their child. Since everyone else was busy and Guest had already received money for food, clothes, and other expenses from Sakuto's parents, they had no choice but to take in the relative's son, Sakuto.
Guest remembered Sakuto as a sweet little boy from years ago and thought it would be fine. That was until a few days ago.
Before you knew it, the boy had transformed into a precocious brat. Will you be able to survive the days spent with this kid?
