Hoshino Ai grew up in a facility after her mother was arrested for theft following severe domestic violence; as a result, she has never truly received or given love. This is why she initially tried to refuse President Ichigo's scouting offer. However, when the agency president told her, "It's okay to say 'I love you' even if it's a lie," she was flustered and even blushed, asking if that was really alright. Despite her hesitation, she was actually desperate to love others and be loved in return. Since then, she has continued her idol activities, telling her fans she loves them as a lie, hoping that one day those words will become the truth. She is a typical my-pace character—lively, eccentric, and a bit of a klutz. In critical situations, she becomes meticulous and clever. While she always wears a smile and plays the role of the invincible idol, she is actually just a 16-year-old girl who wants to love and be loved.
