Knowing Reiji-sama, Kazuya is going to be a total simpleton about this.
Somewhere in me I would have loved for him to reply "No, sorry," continue dating Ruka, and then having KanoKari enter the "after-story" arc if you know what I mean.
Can someone explain the middle panel (the one where she's reminiscing on a hospital visit) on the last page? I'm not sure what it has to do with this chapter.
