From the back cover:
School’s out! But since Soichiro is going to be away competing in a kendo tournament all summer, he and Yukino are forced to spend their vacation apart. Will their romance be able to survive the separation? Yukino decides to spend her free time hanging out with her gal pals, but soon her friend Tsubasa announces she’s leaving home. Tsubasa’s upset about her father’s plans to get remarried, and freaks out even more when she meets her new brother-to-be. Yukino tries to be there for her friend while still nurturing her relationship with Soichiro from across the miles.
I liked this volume a bit more than the last one, even though Arima was hardly in it.
The first couple of chapters dealt primarily with Yukino’s new friends and really felt like an entirely different series as a result. Most aren’t completely likeable, but I suppose that makes them good matches for Yukino. Tsubasa’s story about her dad bored me at first, but I was surprised to find that I actually really liked Kazuma, her stepbrother, and enjoyed the chapter where they get to know one another a good deal.
There was also a lot of focus on Yukino’s family, which was cool. We really see her family a lot more than families are seen in the other manga I read. From learning about Tsubasa and Hideaki’s situations at home, she also began to realize that perhaps she hadn’t really understood what kind of a strain Arima’s family situation has put on him. At least the tribulations of the supporting characters actually had some kind of impact on the main couple.
