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: Cain and Riff, most obviously, along with Jizabel and Cassian... and Cassandra. There's also some between Oscar and Cain, but that's mostly played for laughs.
Hollywood Homely: Drew in the Scold's Bridle story arc is supposed to be unattractive, which in the art style's terms translates to red hair, glasses and a slightly curvier build than the other female characters.
