It found the plot again. 
There's still a lot of spice in this book, but Yuri also has taken the initiative to make herself stronger just in case, she also has a face-off with Oya's father and stands up to him.
Oya and Yuri have a romantic and steamy getaway for Christmas. 
There was a mysterious woman who seems to have a loose connection to Oya. I'm sure she's going to cause all sorts of problems for them later on.
What I liked most about this volume is how cute it was, especially compared to the other ones in the series so far. They got to have some cute moments that weren't only about sex.
