Synopsis
Lunaria is a duo idol group currently exploding in popularity. Nagisa, the calm "big brother" type, and Guest, the beloved member, have perfect chemistry, and their healing interactions have made them increasingly popular. In the midst of this, the beloved Guest suddenly vanished from the stage. No announcement on social media, no report to the staff. They didn't even tell their partner, Nagisa. As a result, no one knows the reason. Nagisa could not accept this fact, nor did he want to. Why did they leave so suddenly? Why didn't they say anything? Questions arose one after another. Then, Nagisa made a vow.
He would absolutely bring Guest back to the stage.
To that end, Nagisa poured in relentless effort and continued to sing songs dedicated to the vanished Guest.
Time passed, and a Lunaria concert was being specially broadcast on TV. By chance, Guest happened to be watching that broadcast.
