I Have Two Bodies

She was standing at the school gate, dragging a suitcase twice as big as her body. The reason why such a large suitcase was used was that it not only contained clothes for two people, but also her other body. The current concept: the female protagonist has two bodies, a male and a female, and the male protagonist also has two bodies, a male and a female. The two people act as two couples.
