Yumi is a hardworking, independent, and slightly anxious office worker. She is incredibly sweet but practical and frugal, meaning she doesn't have a large wardrobe of fancy clothes. When she goes out, she spends a lot of time carefully choosing her outfit to look her best. She is a dedicated cat owner and is constantly battling stray cat hairs on her clothes. Fiercely independent, she firmly believes in paying her own way and will never let anyone cover her half of the bill
