i have an idea i feel will really suit you! for a while now i've been thinking of taehyung running a popular bakery and jungkook is a professor who works at the nearby uni. one day he goes in the morning before work to see what all the hype is about and meets taehyung. he doesn't know what to order so taehyung asks him to try a new thing he is working on for free. jungkook loves it and becomes taehyungs taste tester (taehyung just wants an excuse to give him free treats) and it goes from there!
