Could you recommand UK towns near London for 5 days trip?

Hello from South Korea. I and my husband are planning to visit UK on May for 8 days. (Actually we will stay 10days(5/4(Headrow )~5/13(Headrow)), but I exclude the first and last day since we will be busy those days) I have been UK twice with my friend and my mom so I already visited the famous tourist spots in London such as Bigben, the palace and so on… So this time, we want to visit some UK towns near London. Actually I’m a huge fan of “About time” and I’d like to visit Cornwall that was the movie’s family had lived… But I figured that it is too far and costly London to Cornwall. So could you recommand UK towns near London, which are very attrative and also has reasonable price for transportation. And I and my husband has not much interest on historical things. Instead, we want to enjoy “English mood” like special scenery, cup of tea, beautiful building, of course fish and chips… One thing is that we need to stay in London from 5/11 to 5/13 for watching Tottenham soccer game(SON❤️). So actually we need your recommandation for 5 days in UK towns. Thanks a lot
