Some would say Renako is dense, but she clearly has her own perspectives (and perhaps uncertainties) on relationships, that is her aim is to have good “close friends”.
That said at some point Renako’s “close friendship” is (or can be) interpreted more than friendship, especially to her “close friends”.
Well in any case I wonder if Ajisai will step in the ring vs. Renako’s other “close friends”.
And if Renako ever changed her perspective.
That journey is this series I guess.
