These are like my personal fave of cute mangas that ends in 1-2 volumes, so i don't know if you would agree with me but tbh all are a good story so i think you should read these :3
like phj, sex sales driver, okubyou kurage to koishirazu. those types of short cute manga. no manhua/hwa thanks (ps read sex sales driver its cute af but know haze is mine you can look but cant touch)
