Defying Kurosaki-kun 17

With exams safely behind them, Yu, Kurosaki-kun, and their friends are off on the class trip to Canada! On the plane, at Niagara Falls, a night out in Toronto… Kurosaki-kun's devilish teasing has gone global! When they meet his older brother Sakura's girlfriend, though, Yu can't help but notice how gentle her normally gruff boyfriend acts toward her. He might be having fun with this, but Yu's not about to let her man fall for any other woman!
