While and Xia Qingzi do not appear as main cast names in this specific Korean production, they may be the translated names of minor characters or roles in a related adaptation or web novel that inspired the series.

The tiger, on the other hand, represents the unbridled energy and ferocity of the natural world. Its appearance in the poem serves as a reminder of the awe-inspiring power of nature and the fragility of human existence. The tiger's presence also alludes to the Buddhist concept of the "tigress," a symbol of fierce and unrelenting spiritual energy.

In their collaboration under the banner of The Crow (a title that evokes both the graphic novel tradition of vengeance and the omen of death), the chemistry between Zhong and Xia is rooted in melancholy.

The story concludes with a striking image that signifies a return to balance: a full moon hanging over a field where the Crow and the Tiger —once symbols of death and raw power—drink peacefully from the same stream. This ending suggests that through Wanbing's sacrifice, the cycle of violence is finally "full" and has come to an end, allowing for a new beginning.
