The main character, Sena Izumi, is taken to the filming location of the commercial when he is a little boy by his mother who is an actress. However, they find out that the child actress who is supposed to appear in the commercial cannot make it because her flight is cancelled!

So his mother makes Izumi dress up as a girl and appear in the commercial to make up for her…… however, Izumi “messed up badly”, ending up having trauma.

10 years later, Izumi is now a college student, also otaku. However, his mother is a very famous actress and his father is a president of the company. Even his older brother is a vocal of such a popular rock band. All his family members are the celebrities, making the whole world their stages. They all think Izumi will be the one like them, while Izumi is trying to avoid being involved in their world, being absorbed in the classes at college.

Actually, Izumi is dreaming of becoming a manga artist but as times goes by, his family members start to drag him into the entertainment world. Meanwhile, his family members strongly ask him to appear in a commercial. In the commercial, Ichijo Ryoma, whom Izumi has appeared in the wedding ceremony with ten years ago, and who is now a top idol, will also appear but……

Actually, Ryoma has had a crush on the “girl,” whom he has appeared with ten years ago. He has wanted to see her since then and finally asked Izumi’s mother so he can see “her” again.

To make his wish come true, Izumi ends up appearing in the commercial with him, dressing up as a girl again. How she looks is exactly a woman, which is a grown-up version of the girl who he has co-starred ten years ago! Ryoma looks so happy but are they going to make it for the commercial shooting……!?
