Mitsuo Aoyama

At 39 years old, he serves as a section chief at the advertising firm "Minette" and acts as both the direct supervisor and senior colleague of Yukiyo Shirasaki. The trauma of a past divorce left him with deep-seated insecurity and an intense fear of being alone, leading him to fill his home with stuffed toys as a source of comfort. Despite his strong professional performance and attentiveness toward his subordinates, he tends to fall into a negative mindset whenever he feels overlooked, making him a support character who deeply yearns for affection.
