Chika Idol wo Kage de Sasaeru Ore
地下アイドルを影で支える俺
Natsukawa, a classmate with a bold and lively personality, and Kageyama, a quiet and low-key student, seem to have no real connection. One day, Kageyama receives a private message from Natsukawa asking him to meet at their usual karaoke location after school. They spend time together there, and Kageyama presents her with something he was asked to prepare beforehand.
