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.
Ho Yay: Present in Kaoruko's story about her and Fumio's shared past life, as a knight and a common soldier, who fought side by side and were executed together. Both were supposedly male, though they are not drawn as such. Their current incarnations have a distinct Les Yay vibe as well.
