For anyone wondering or caring about the pacing, the cohabitation started on April 12th. When was that you ask?
59 chapters ago, Chapter 255.
Reiji sure likes to troll the readers when he pulls stuff like Kazuya saying that just a little over 2 weeks left, because the date is May 2nd. (But bruh, Paradise covered 3 days in 43 chapters, so this is an improvement, bruh)
Though I have no idea how that May 18th date came to be as equal to 1 month. Someone please enlighten me.
