Love interests who are the arrogant, high-born "young master" type who eventually goes into full remorse mode (Kazama Chikage-style) are so rare in Japanese otome games. I really love this type. Another type I like is the sexy playboy, but I mean genuinely sexy, not the hollow kind of "sexy" that's just for show. That type is pretty rare too. (Ymir from Yumekuro)
