EPISODE CONTEXT

As the series premiere of a 12-episode season, this episode carries the full weight of setup—introducing the central conceit of Mizuto and Yume's ex-couple-turned-step-siblings dynamic and the blended family surrounding them. Everything here is foundational, establishing character personalities, unresolved tensions, and the competitive dynamic that will escalate across subsequent episodes. It effectively plants the seeds for a season-long exploration of whether these two can maintain their sibling charade or if old feelings will inevitably resurface.
