An introverted young man working as a delivery driver for the food app Eatza in a quiet rural town dreads his shifts because of one regular customer. She is a tall, beautiful woman with an intimidating glare and an unfriendly aura that makes him so nervous he drops off her order and flees as quickly as possible. One day, she finally speaks to him, and her gentle voice sounds exactly like that of Hanae Fuwari, his favorite VTuber. While he does not immediately connect the two identities, the shy woman, who is indeed the person behind the popular online persona, shocks him further by offering to pay him just to sit and chat with her.

The unnamed heroine has become a shut-in due to crippling social anxiety and low self-esteem, largely stemming from years of bullying and gossip about her tall stature and mature figure. She lost previous jobs and struggles to even visit a convenience store, leading her to order everything for delivery. Her VTuber activities as the cheerful Hanae Fuwari provide an outlet, but she longs to overcome her fears and reconnect with the real world. Recognizing a kindred spirit in the equally introverted delivery boy, who grew up being teased for being unusually short, she sees befriending him as a first step toward personal growth.

The developing friendship navigates a series of awkward but heartfelt milestones. In one early arc, the delivery boy helps her attempt a trip to a convenience store, a simple journey that feels monumental to someone paralyzed by social anxiety. Their relationship deepens as they learn more about each other, though a central dramatic irony persists: neither realizes their true connection. He remains unaware that the intimidating woman is his streaming idol, and she does not know he is one of her most devoted fans. This tension escalates in later story arcs, such as when a convenience store clerk misidentifies them as a couple, creating a new layer of awkwardness between them. The plot thickens when the delivery boy discovers another Eatza driver at her door, triggering feelings of jealousy and fear that he has been replaced, forcing him to confront the true nature of his feelings for her.
