Volume 4 of the Chinese translated
Yasashii Ryu no Koroshikata arrived at Kinokuniya. I really like Uraniborg's two male ancestors, Cepheid and Alphard. Alphard is so gentle and noble. In contrast, Cepheid is a total flake and a shameless flirt (even dares to kiss Uraniborg's true love, Arkangel). Hard to believe how he ever became a Dragon King, particularly the one who started the whole cycle (or curse) that made his descendants willing to sacrifice their immortal lives for their respective human loves.
