Ichigo Saitou is the president of Ichigo Productions, the agency Ai belongs to. He is a father-like benefactor who scouted her off the streets, raised her into a legendary idol, and protected her secret pregnancy until the end. Visually, he is a distinctive man in his 30s who always wears a yellow beanie, sunglasses, and sports a mustache. While he is a cold-headed realist who understands the inner workings of the entertainment industry, he is actually a man with a 'cold exterior but warm heart.' Although he was furious about Ai's pregnancy, he eventually devoted himself heart and soul to her and the unborn children, staying by her side with a deep sense of responsibility and affection. In his 40s.

During the time he cared for the pregnant Ai Hoshino, Gorou Amamiya was a reliable supporter who, despite feeling deep despair and agony internally over his favorite idol's sudden pregnancy, silently helped with her secret delivery out of professional duty and pure fan affection. Usually a blunt and calm obstetrician at a worn-out rural hospital, he became a primary physician and the only comfortable confidant Ai could open up to. Although he often worried and nagged her about her reckless behavior as a young pregnant girl, he was a warm and dedicated person who sincerely wished for Ai to be happy as both an idol and a mother, risking his life to protect her secret. Mid-30s.
