An end to a wonderful manga! With good translations to match. Thank you for letting us experience this at this quality. Damn, never been this fulfilled.
I don't know where this is going but I'm gonna throw out a crack prediction: Chako is going to confront Nagi at some point and her feelings are running high, she's saying all kinds of stuff. Nagi? Nagi just gives her a kiss because it seems like it would make her feel better
Oh my, I hope it goes down the age gap romance route! Most likely not since usually it's the first guy to do a nice thing with sparkles that the FL gets with but aaah to hope. Thank you for the translation~!
