Princess Bari was a selfless princess who gave up the most important thing in her life to save her parents. She gave up 10 years of her life (that must be what's important for her) I believe the title is a metaphor. How Yohan gave up his most special friend for the life of another is an embodiment that he was a "prince bari"

The name is" Prince Bari" but there was no one with that name. Why?
