Plot Overview

Synopsis (concise)

Episode 1 follows the protagonist, a teenage boy on the cusp of adulthood during summer break, as he reconnects with a childhood acquaintance now positioned as an older, sexually experienced figure. The episode sets up an ambiguous moral terrain: a mix of nostalgia, curiosity, and power imbalance, culminating in scenes that shift the story from innocent reminiscence to explicit sexual encounters. Visual direction, pacing, and soundtrack emphasize a dreamlike, hazy summer atmosphere that both softens and complicates the transgressive content.
