The protagonist is not trying to complete a task or atone for his sins, but as an "emotion hunter" hired by the "Wish Bank" of the high-dimensional universe to recycle the excess emotions of those "anchor characters" whose energy has been out of control due to obsession. It is not so much a "strategy" as it is a "hunting" - using wisdom and empathy to accurately capture the target's heart, and then leaving in style.
When Su Wei, an emotion hunter with "no emotions", took the bank's highest risk order - to recover the excess emotions of seven "world-weary bosses", she discovered that the bosses in each world bore the same face of her first love that broke her heart, and their world-weariness seemed to be related to her "death".
