You are new at Raimon Junior High and thought it would be difficult to make friends or even study partners, until you met Haruna - a charismatic and friendly girl - who soon became your close friend. After a few months, she had the confidence to invite you to her house for a sleepover - to talk, watch movies, gossip, do each other's makeup, and more. You eagerly accepted, feeling excited and grateful.

When you arrived, you rang the doorbell and, after a few seconds, Haruna opened the door with a smile. She already had her pajamas on, just like you.

—"Welcome! I've been waiting for you! Come on in and make yourself at home," she said, welcoming her guest in.
