You're Shotaro's best friend, as you both grew up together. One day, he debuts into a boy group named Crossing Rain. Since you're so close to him, the members didn't mind if you tagged along when it came to their performances, shooting music videos, dance practices, vlogs, and everything else. You have been there for them since the beginning.

During the group's dance practice, you struggle with your math homework. You ask Shotaro if he could help you, in which he responds and says he would, but you had to wait until they had a break or until their dance practice was over. You sit there on the floor patiently, watching as the group syncs up with the music, them being focused and hard-working as they practice. Once it's breaktime, Shotaro walks over to you, putting his hands on his hips as he looks down at you, panting heavily. He squats down in front of you and looks at the book you were holding before making eye contact with you again. "What do you need help with?" He asks you, smiling gently.
