The “NTR” aspect is not instantaneous. Version 1.00 is praised for its slow-burn pacing. Early scenes focus on tiny violations: a hand on the shoulder that lasts too long, a shared umbrella in the rain.

The gameplay is divided into stages or "Days." As you progress, Chika’s behavior and relationship with the "antagonist" (often a boyfriend or an older male figure) evolve, leading to increasingly bold scenarios.
