Can we all get over difference and just be happy with what we get? Be it Senpai/Kohuai or Senior/Junior we all are fking weebs and are gonna read it anyway.
I mean Senpai/Kouhai is fine. I always thought Junior/Senior felt wrong because that relationship isn't quite the same concept in the US as it is in Japan, so Kouhai/Senpai being foreign words feels like a reminder of how the dynamic is supposed to be.
