This would test their relationship as they face various challenges along the way.
The theme of self - discovery is also prevalent. Both Shana and Yuji are complex characters. In fanfictions, they often learn more about themselves as they interact with each other. They discover new aspects of their powers, personalities, and values, which in turn affects their relationship.
