Tbh I never considered dropping this manga in the past 213 chapters but this is really pulling my strings. So much happened over the last chapters and there was finally some time to catch breath, this sh*t pops up. It's so random and unnecessary.
Not so sure but I think there is a translation mistake. I was a bit confused when Nise said that one day has passed since the last helicopter landing, so I looked at raws and translated them. And it says there that "it feels nostalgic" and not "which means that one day has passed".
