Aitsu no Yubi de Nurechau!: Wagamama Ouji no Kari no Bigaku

Sumire has been assigned to a publishing company as a novice hair and make-up artist. On her first day, she suddenly witnesses a man and woman in the act! Moreover, the man who looked so familiar is Atsuki, a hugely popular model. Knowing she saw him, Atsuki locks his sights on her. He's overbearing and a narcissist, and Sumire think nothing of him at first, but... Huh? He's doing it with the Editor-in-Chief right now!? He calls out to her... "You should come here, too, Sumire!"
