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: Fading Hearts
Moe: — Any of the female characters, but especially Rina. Ryou finds it "really cute when she acts shy" and when she eats too much at once, puffing her cheeks out.
So Bad, It's Good: JesuOtaku has gone on to call it "The Room of Visual Novels," because of its terrible dialogue, many grammatical errors, and overly serious story (not to mention how one of the characters is a survivor of the Y2K bug and is part of a group called the Y2K orphans... yeah) Hervideo on it shows highlights that will give you an idea on why it deserves that title.
