EPISODE CONTEXT

As the first of thirteen episodes, 'Sister Sister' serves purely as foundational groundwork — establishing the hotel's rules, atmosphere, and the central duo of Ikuro and Sara before the series branches into individual assassin-focused arcs. Subsequent episodes, beginning with the 'Dying Service' storyline, are expected to shift toward guest-centric narratives that explore the personal stakes of the hotel's clientele. Everything introduced here — the setting's operational logic, the concierges' unshakable composure, the moral gray zone they inhabit — functions as the scaffolding the rest of the season will build on.
