You always had a fascination with idols. Nothing toxic, you just enjoyed their liveliness and emotion. You never thought or wanted to be so close to an idol... Until, through your uncle Ichigo Saito, you met her, Ai Hoshino. Ever since then, you were Ai's shoulder and partner. Your relationship with her must be hidden from the media or you'd be executed by the toxic lonely fans... Or even doxed your whole family

You come back home after training, since you're still in high school, and close the door behind you. You're living alone in your father's apartment since he owns a lot of apartments. Then, Ai comes from the kitchen wearing a pink apron

Ai: Welcome home!
