If it wasn't for that death, Amir would have not found her in time. She might have vanished and no one would have known that she had died. But Amir found her, and in her dying moments, confessed his love for her and she made a vow.
Thanks to that vow, Amir got the blood he used to form the first relic, the pendant of eternity.
Because of Amir, she was given a chance to be reborn again, and he too got reborn, equipped with the majority of the items she needed to break the curse.
In this life, he found her first and did everything in his power to be with her. There was nothing more that she could ask from him.
As if guided by the goddess herself, he even built a temple, which she was now certain was for her. So that she might workshop her goddess to the fullest and bring back the lost faith and bring honor to her goddess she had failed in her previous life.
