Feeling rather conflicted about them still not calling each other by first name (at least when they are alone together). That seems like one of Yamada's (or should I say Yui's?) weak spots. If Kase-san wants to make her melt like butter she definitely has the Y-bomb ready haha
Other than that, very cute. How much do you bet that if that mixer actually happens Kase-san will do one of her famous explosive interruptions at the last moment? She loves chasing off guys around Yamada more than she loves running at this point lol
