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.
Narm - The constant talk about tears can come across as something very creepy.
The Scrappy - One of the main complaints with the series is that Shinichirou, the protagonist, is too bland. And that his obsession with Hiromi's tears is cranked up to serial killer levels. Another prospect for future serial killer levels of creepiness is Jun, Noe's brother, who acts like an egoistic jerk throughout the entire series.
Additionally, Hiromi is often hated for being slightly less interesting than the other girls on the show. Thus when she got together with Shinichirou, the resulting Internet Backdraft bore out from the Shipping Wars.
