Yabai Idol no Manager ni Nacchatta Hanashi

After reluctantly taking a job as a manager, the first super-popular idol you're put in charge of, "Maron," turns out to have a secret side... While Maron shines bright on stage, in her personal life she's a high-maintenance, quirky girl who can't put down her cigarettes.
To keep the true face of the "perfect idol" Maron completely hidden, you'll have to give her all the support you can as her manager!

A two-faced idol x a caring manager. Starting from the smoking area, their story begins!
