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.
Viewer Gender Confusion — Makoto is a girl, despite having a boyish hairstyle. Subverted for Rin later after her introduction; Sakura (and the readers) are first introduced to Rin as a girl wearing a dress with Girlish Pigtails, without any indication of Rin's biological gender. Tsuyoshi eventually reveals that "Rin is a guy" while Rin considers herself to be female.
