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.
Tear Jerker: The canonical ending is so touchingly heartrending that the author didn't even try to make it funny. Somehow, even with the chibi art stye, exaggerated characters and all, its still a tearjerker.
The FeMC's version of October 4th, including a special added scene the author made. If you didn't get a little choked up at the FeMC holding Shinjiro's hand while he lays comatose in the hospital and two other characters are aruging about whether or not he'll wake up, YOU HAVE NO SOUL.
