In one of the chapters Kana-chan refers to Taichi and Chihaya as the moon and the sun. Which one is the moon and which one is the sun?
I believe that Chihaya is the sun while Taichi is the moon. Chihaya’s light and happy exterior can be compared to the sun, while Taichi’s deep and somewhat darker interior can be likened to the moon. Moreover, in the (former) team dynamic of Mizusawa, Chihaya was generally the one who would push the rest of the team to work hard. Taichi, on the other hand, was always there to support the team and keep it together when things would get tough. Chihaya is the sun in the sense that she constantly spreads her light to everyone, while Taichi is the moon who is able to shine just the right amount of light in the darkness or in struggles.
However, if you observe the panel, Taichi’s face is somewhat lit up, while Chihaya’s face has a downcast. Perhaps Suetsugu-sensei is implying that Taichi is actually the sun while Chihaya is the moon, although I don’t see evidence as to why.
I honestly don’t know the actual answer to this question, and am now quite curious to find out. If Chihaya is in fact the moon and Taichi is the sun, what reasons aside from the lighting of this panel are there to support this? On the other hand, if Chihaya is the sun and Taichi is the moon, why are their faces in this panel colored reversely? Any ideas or sentiments would be greatly appreciated!
