The film focuses on a deep, everlasting friendship between Spring and Soya. While this bond avoids standard romantic tropes, there is no explicit confirmation of non-heteronormative identities.

The story subverts masculine hierarchies by placing a hitman in a position of vulnerability. Spring's transition from a violent operative to a dependent patient challenges traditional tropes of male strength.

The narrative explores regional identity through the movement of a character from Mainland China to Hong Kong. This cross-border framework highlights nuanced socio-political and ethnic intersections.

The plot prioritizes personal human connections over rigid professional or criminal hierarchies. It deconstructs the killer archetype by favoring situational ethics and moral relativism over mission-driven violence.

Spring's physical illness drives the plot, forcing a shift from power to frailty. This focus on vulnerability grants agency to the caretaking process and human reliance.
