Memoir 1: Maria, a sweet and affectionate girl raised in an overprotective household, begins communicating with a man she randomly met online. Triggered by her self-taken photos uploaded to the internet, she receives a DM and lies to her parents, claiming she'll be staying at a female friend's house, then heads to a photo studio run by the man. Maria shyly poses in her first cosplay outfit, but her appearance excites the man and further captivates him. During the shoot, her mother calls, but despite trembling at the sound of her voice, Maria hangs up, holding onto hope for freedom from her suffocating control. Inside her lies a dutiful, obedient honor student, yet she struggles to suppress her true desires. And beyond this lies the man's true nature, which begins to reveal itself—gentle on the surface, but with darker intentions. Amidst a mix of tension and arousal, Maria gradually starts confessing her innermost feelings.
Memoir 2: Recognizing Maria's potential as a natural female masochist from their previous encounter, the man introduces her to someone he knows named Hayashi. Hayashi is a well-known dominant figure in the scene, and he prepares a cosplay outfit of her favorite character, arranging a photo shoot in an abandoned building. Calmly clicking the shutter, Hayashi begins to dominate Maria within the eerie silence. Though initially confused, Maria surrenders to her hidden desires, unleashing her repressed sexuality as scenes of taboo sex and body-opening acts are recorded. Through this experience, Maria escapes her overprotective upbringing and embarks on a journey of self-discovery, unveiling a new side of herself.
