My Air Doll Girlfriend centers on lonely, socially anxious Gabriel, who lives alone with Seraphina, a life-sized silicone air doll he treats as his lover. Initially emotionless and programmed to obey, Seraphina gradually gains self-awareness through daily interaction. Curious about the outside world and human warmth, she develops jealousy, longing and independent thoughts, leaving Gabriel torn between paranoid possessiveness and tender affection. Their quiet days are filled with small conflicts: hidden cracks, secret outings, and comparisons with warm-blooded real women. After countless breakdowns and desperate attempts to keep her intact, Gabriel breathes his life into her. At dawn, Seraphina finally gains her own warmth and faint breath, completing a tender, bittersweet miracle of mutual salvation rooted in lonely love.
