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.
The awkwardly tacked-on romance between Owaki and Yoshida. It's probably supposed to make us feel sadder about their deaths, but it comes across more as "HEY THERE IS A BOY AND A GIRL AND NOW THEY WILL FALL IN LOVE."
Viewer Gender Confusion: Owaki is male with a somewhat female face and feminine haircut. You would think Owaki and Yoshida are lesbians up until his dream where he is a caveman with a stubble or when he enters his hole.
