Just read the next chapter. Another funny one, and Takagi was so sweet throughout (well, almost).
Some stuff I had to look up:
page 2:
γγ£γ¦γγγγγγ
It seems to be an abbreviation of γγ£γ¦γγγγͺγ (source), and judging from the frequency it appears online it must be a fixed expression. It basically means βIt canβt be done/ I canβt do itβ.
γγγγγγγThis is basically γγγγγͺγ (canβt be helped, thereβs no other way), with γͺγ contracted to γγγ ( source)
page 6:
γͺγγ‘γγ£γ¦ A fixed expression meaning βJust kiddingβ. Iβm not sure what original words it is contracted from, if any.
page 14:
γγ£γ¦γγ£γγI believe this is a contraction of γγ£γ¦θ‘γγγγ(source) (letβs do it/shall we do it)
Plot related thoughts (spoilers)
I found the last two pages hilarious, especially the all-innocent and happy Nishikata thinking that Takagi may be a good person after all. All his suspicions that were tormenting him for the whole chapter are gone, only to make him more vulnerable to the punchline. His asking for the juice back was very funny too. Donβt worry Nishikata, any kind of studying is good for you, even if itβs not useful for this specific test.
