it is not from this author i think but there's a manga like that where a female in her thirties?? someone who is not old nor young fell in love with her delivery girl. It was wholesome. I think that FL there started working at home due to an entitled man and female coworkers name-calling the FL (as sl*t) that led to trauma and ruining her work life . She became secluded but then she met the bright delivery girl who distributes her own made flyers with cooking recipes of her grandma.
i forgot what title but I read it in dynastyreader
