I don't get this one, they seem to already be saying what they are.
Am I missing some context?
Again, title mistranslation....
It's more "arrange the older childhood friends order based on their closeness to neighbour shota-kun"
tl;dr arrange from horniest to least
Edit : This almost fly over my head, but apparently, it subtly implies
arrange them based on number of times they did it with shota-kun
