Three cycle of incarnation

In the end she really died...well, at least she thought she died. It turns out the suffering she went through was just a measly mortal incarnation. It turns out that mortal life was one of three, needed for her to experience mortal hardships. This trial to make her ascend into an immortal with ranking that of a high goddess.

But what about the mortal man she left behind? What connection did he have to the Celestial black dragon prince they keep telling her disappeared because of her?
