The protagonist isn’t completing missions or atoning for past sins. She is an “emotion hunter,” hired by the “Wish Bank” of a higher-dimensional universe to retrieve excess emotions from “anchor figures” whose obsessions have thrown their energy out of control. It’s less a matter of “winning them over” and more like “hunting”: using intelligence and empathy to capture her targets’ hearts, then leaving with a flourish.
When the “heartless” emotion hunter Su Wei takes on the bank’s highest-risk assignment, retrieving excess emotions from seven “world-weary powerhouses,” she discovers that every world’s boss has the same face as the first love who broke her heart. And their weariness with the world seems to be connected to her “death.”
