With that been said can anyone tell me...where I can get yokozawa story plsssssss

As far as I know, there is no manga about yokozawa, but there is a light novel. I might be wrong, and meanwhile you finding the right answer, here is the link to the novel https://www.novelupdates.com/series/sekaiichi-hatsukoi-yokozawa-takafumi-no-baai/
