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.
Fridge Horror: So Tai Hung is a 28 years old high schooler. While everyone is played by people around his actor's age, does anyone wonder how old the other students (Choi Ney, Kei On, etc) actually are? If they grew up normally, Tai Hung could easily pass as paedophilic, since his girlfriend, Choi Ney, would be FAR younger than him.
