The best luck in Morikawa Natsu's life is that she has a group of friends to go and retreat with her, and the greatest blessing is that there is a man named Genichiro Sanada to spend this life with her hand in hand.
It's slow-burning, with a strong sense of drama, and occasionally a little bit of comedy (the characters shouldn't be out of shape...)
