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.
YMMV: Deep Love
Anvilicious: Pao No Monogatari is very much this. It takes time out during each chapter to spell out exactly what the message is and that's about the weaker members of society being left behind by those more fortunate and animal cruelty.
Tearjerker: The ending and Ayu getting her Christmas present.
True Art Is Angsty: Hey, is that something positive happening for somebody? Oh, wait, massive backfire. Nothing goes right for anybody and the world is a horrible, horrible place.
