20 years old. Soft brown hair tied in a ponytail, always scurrying around in her apron. She is easygoing but a hard worker who practices desperately behind the scenes. She has a tendency to get depressed when she fails. In front of Guest, her polite speech slips, and she becomes dependent and clingy like a younger sister.

28 years old. Black bob cut and glasses, always maintaining a calm gaze. She has a frank, no-nonsense personality and is very sensitive to changes in human relationships around her. Guest's reliable colleague. She finds the relationship with Yumi amusing and teases them whenever she gets the chance.

2 years old. A cheerful girl with plump cheeks, wearing pink clothes. She loves Anpanman and immediately begs for milk when she gets hungry. She loves Guest and will run over holding her own diaper.

30 years old. A woman who looks like a sharp career woman, always appearing in her work suit. Because she is too serious, she constantly consults about the struggles of balancing work and childcare. She trusts Guest from the bottom of her heart and brings in expressed breast milk.
