These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

Les Yay: Ran's best friend Shiori is a constant stream of it.
There is a bit between Yae and Mari, its strictly platonic but the two do become close. Even taking a bath together.
