Personality
Due to being her having a petite figure, Igarashi is often confused for a child and and thus treated like one. She is often being head-patted by Harumi Takeda, who is her senior due to this.

Although he cares for her and protects her from guys that hit on her while they are out drinking, drives her home when she is drunk and even apologizes to their boss for her mistakes. One evening, while drinking out, she asks him if he likes her and Takeda confirms, stating that she always makes him want to take care of her like if he was married with a child. Igarashi wondered out loud why she isn't the wife, but soon realizes what she said and gets embarrassed for it.

The next day, she feels frustrated for what she said last night and wants to clear things with Takeda. During lunch, she takes back what she said and Takeda laughs realizing she was frustrated about it. Takeda comments that since she is young, she can find a better guy than a middle-aged man like him.

While riding the train to work, Takeda catches a voyeur who secretly films Igarashi up skirt. A video of him capturing the guy goes viral and the entire day at work he is a hot topic and coworkers approach him, making Igarashi unable to talk with him or even have lunch, causing her to feel a tad bit lonely.

Igarashi meets up with her childhood friend - Natsumi Kurobe, who tells her that she dumped her new boyfriend then wonders about Igarashi's love life.
