Is Nanako ever gonna admit that she sort of(?) cheated on Eiji with Koto in the last chapter? Or is the author just going to drop it and only use it for a running gag.
Like "Haha! Your girlfriend went on a date with another girl and almost made out with her, almost giving her her first kiss in the process, and you will never know that your girlfriend might have feelings for other women that may match, or possibly surpass, her feelings towards you."
...Funny?
