Oshi ga Joshi ni Narimashite
Hitomi Nakajo is an office lady who is a big fan of the stage actor Toma Kiryu. Watching Toma on stage was the thing that brought her the most joy, until she was crushed by the news that he was suddenly retiring from acting. Then one day, Hitomi got a new boss named Shuichi Takagi. To her surprise, Shuichi turns out to be Toma Kiryu, now using his real birth name after retirement! Furthermore, Shuichi is also the company owner's son. Hitomi tries to treat him like a normal coworker, but her inner fangirl keeps getting the best of her, making her panic and sound cold, whereas the other ladies in the office all smile and fawn over him. But Takagi is intrigued and takes an interest in Himomi because she doesn't act like the other girls.
