One minute walk to love in cosplay 徒歩1分のコス

A woman who works as an office worker and is shy in love falls in love with a man who works part-time at a convenience store a minute’s walk from her home. She even puts on makeup and dresses up to go to the late-night slot once a week where he works, but there is no response and no progress.
When she talks to her only best friend about it, she is told that if she goes there in cosplay, he will indeed notice her. The protagonist hesitates due to embarrassment, but changes her mind and goes to a convenience store in cosplay, thinking that she can go as an anime character of a female hero whose face is not clearly recognizable with a mask over her eyes, and late at night when no one else usually comes around.
Inside the store, she meets the male clerk. She is taken aback, but the response is not bad, and more than anything, she is happy to get a reaction for the first time. But then a similarly masked convenience store robber arrives. The clerk suspects them to be fellow robbers, but the woman takes on the role of her character and the two cooperate to eliminate the robbers. It turns out that the male clerk was actually interested in the woman, but had not approached her because of her shyness.
