Star-Crossed!! Vol. 4 Manga
Azusa lives for only one man: Chika-kun, the cutest and most popular star in the idol group Prince 4 U. She goes to the shows. She watches the interviews. She buys the latest exclusive merch. But one concert changes her life, when she accidentally dies trying (and failing) to save his life! It turns out it was all a mix-up, and God agrees to return the two of them to Earth - but fate's mistakes don't end there, as they each wake up in the other's body!
