giving the information from Honey & Mustard (Mitsuki and Kaori, age 27 then) and Honey & Mustard 2 (both now age 31), four years have passed. We also see that Chiho and Mai ditched the food truck and opened their own restaurant. Is nice to see they got their dream come true.
Everyone is happy.
I have to wonder if I am correct in feeling its a shame that it took fifteen years for the two to get together, since they have technically been together the whole time, just not doing it.
