-Rin is master of cheesy pickup lines (i.e. are you Cinderella bc I can see that dress coming off at midnight)
-Miku never gets them
-Ever
-So Rin just comes up with increasingly more obvious ones until she just flat out asks Miku out
-Whenever they plan ~fancy~ dates they end up just canceling the reservation and staying in, ordering pizza, and watching increasingly bad romcoms (Miku's choice) and action movies (Rin's choice)
-They argue a lot about what movie to watch so half the time they have to get Len to pick and he chooses a film noir that they both hate
-One time as a joke Rin bought Miku a whoopee cushion "to introduce her to the wonderful world of pranking" but now she carries it everywhere which has led to some pretty embarrassing moments
-They both overstuff themselves on holidays but who doesn't
-Rin basically only eats fast food and oranges but Miku will eat anything so long as it's covered in chocolate
-Obsess over each other's birthdays
-They fangirl together (especially over Drarry)
-Start flame wars in comments for fun
-Will probably set the world on fire one day tbh
