So two things could happen here:
1.)mami explained the reason why she broke up to Kazuya to his grandma and having bad flashbacks of Mami(ngl grandma looks chill with mami)
2.) All of them will learn Chizuru's and Kazuya's secret
I knew this was gonna continue to that Mami DM'ed Kazuya's grandma, thought Author-san forgot about this... Movie arc done, now the "Business" arc I think?
@Lustrist no, she isn’t. If you’re joking, the you got me, if you’re not, then either you completely forgot what a pain mami is or didn’t read any of the chapters with her in it. To be fair it had been many chapters since we last saw her
