Mmmm yeah Kase is a thirsty girl ;3
Also sorry if this question is stupid but during that chapter, did Kase actually get a glimpse up her skirt before Yamada closed her legs or did she close them too fast? 
And yeah I read plant appointee and straw hat and yeah Kase's love and admiration of Yamada is adorable omg i wonder how long in the timeline it took for her to  work up the courage to talk to her finally
