They're doing allright for a long distance relationship.
50 minute train journey is a long distance? Yamada popped over just to give her some flowers in the 1st chapter.
that dialogue sounded weird for some reason like she could've said that she wouldn't date the prince or smth
I get the feeling as Kase is the tomboy that her only rivals can be dudes which is... huh.
Yamada has got jealous of other girls around Kase but I am not sure Kase has ever got jealous of girls around Yamada? Been a while since read it all though.
