I recommend the novel "Dimensional Grocery Store" to you. The plot of this light novel is about a young boss of a grocery store. The door of his shop leads to various worlds. One time, a girl came to the door. She seemed to have her eyes on the position of the lady boss and was scheming to take down the high mountain of the store manager. However, during the process of the transaction, they gradually discovered the true feelings between them. Although I'm not sure if the male protagonist and the female protagonist are from the same town, since the male protagonist runs a car repair shop and the female protagonist works in the city, this book might meet your needs. I hope you like this fairy's recommendation. Muah ~😗
