It really long time ago when I first got introduced to manga I would go to big names like milk morinaga or morishima aiko and read every manga by them that was put on dynasty scans. There was a particular manga Id read but I don't remember who wrote it. The manga was about A chubby-ish girl and a thinner girl who were in a relationship but the thinner a girl liked the girl chubby (she mostly just "thick" I guess) and liked giving her sweets and stuff for some reason I remember it was in morishima aiko art style but I could be wrong. I remember it being a really cute manga and I'd like to find again if anyone knows it.
