Redemption in the name of a saint

Taking care of her mother-in-law with dementia, her husband's moral harassment, and domestic violence. For housewife Ryoha, her son Tsubasa is the only meaning of life.
However, Ryoha loses Tsubasa in an accident.
A world without hope and love. She throws herself into a raging river in a heavy rainstorm.

But destiny takes a turn!
Ryoha is transported to another world as a "saint" who heals people!
"Saint Suzuha. Please save this world."
Suzuha suffers from the conflict between her choice of death and her healing power. Furthermore, her power gives the saint a "defilement" that corrodes her life.
In order to exorcise the defilement, she must perform a ritual with Prince Vix... a sexual act...
"Please accept me."
It was this world and you who scooped me up after I had given up on living.
For the sake of my beloved and the world, the redemption of a dying saint begins.
