Long story short, Kase-san is a great read. Throughout the five volumes, you get to see their relationship grow along with the art. It’s a coming-of-age type story and it displays all of Yamada’s insecurities and anxiety as heart-wrenching as it is. But it also shows the meaning of communication and how it ultimately fixes just about everything in these romance stories but it seems like nobody ever wants to talk. Sorry for the rant.
