@horsewithnoname I'm rereading from Chapt 1. Lots of stuff I missed. Mix of old and new tech: She has a1970's flap digit clock by her bed.
Chapt 2 TV announcer: "Generic Terra is truly a romantic undertaking for all mankind". Generic Terra is clearly the Ramiel in the sky after rereading Ch2. The TV announcer actually says Generic Terra is romance for mankind. So "Kowloon Generic Romance" actually refers to the second earth they're making when readers are assuming the title refers to love between the two main characters?
Lots of foreshadowing of amnesia like people are speculating. "Righteousness emanating from this juicy, boiled gyoza dumpling" from him in Ch1 is the exact same thing she told him in the flashback when they first met. Constant fiddling with the glasses. Numerous mentions of "nostalgia".
