Marmalade Boy: Collector's Edition 1

"Miki's life was pretty ordinary until the day her parents told her they were swapping spouses with another couple!

Miki isn't exactly thrilled with her new situation, and though Yuu is super cute, he's also kind of a jerk. Can Miki sort out her complicated feelings for him and come to terms with her new family?"--
