This is a story about rebirth.
Haruno Sakura, one of the new Sannin, after experiencing the four battles and the final battle of the Valley of the End between Naruto and Sasuke (Chapter 699), returned to the beginning (infancy) and relived the story of life.
(There should be no CP direction, there may be CP in the extras)
PS is a rebirth after all, so hangups are bound to happen!
Maybe it will be compared to Our Lady in some way?
Why is there no update?
