Casting features an all-Korean ensemble fitting the cultural and historical setting, with no race-swapping, forced diversity, or identity-based changes. Themes revolve around destiny, family revelations, and police work contrasts between eras, including a competent female criminal psychologist who aids the male leads organically as part of the team rather than as a vehicle for feminism or systemic oppression narratives.

There are no LGBTQ+ elements, social justice lectures, critiques of traditional norms, or creator statements pushing activism; reception focuses on plot satisfaction, acting, and comparisons to similar thrillers like Signal, with zero backlash over wokeness or DEI. This traditional storytelling prioritizes suspense and resolution, free from contemporary political messaging, making it a refreshing escape into unadulterated genre fun.
