This was a pretty intense volume.
Yuri has been kidnapped, again, but this time the reason doesn't start off as personal. 
We meet Oya's brother, who we didn't know existed until now. And he's nothing like Oya. He's sadistic, and cold. 
I like the volumes that are more plot heavy. The ones that only explore Yuri and Oya's relationship are still enjoyable to read, this is a dark romance after all, but I do like to have more plot.
I am interested in seeing how Yuri's friendships change after this. Aside from her basically lying to them for a year. While her relationship with Oya might've been the thing that saved their lives, I know things will be different between them.

Writing this review was challenging, since I already started the next volume.
