Mama wa Boku no Mono

A young man harbors an intense obsession with his best friend's mother, a beautiful and kind woman who has always treated him like family. Unable to control his desires, he begins to manipulate situations to get closer to her, exploiting her trusting nature and the opportunities that arise when they are alone together.

As his fixation grows, he devises increasingly bold plans to possess her, crossing boundaries that should never be crossed. The woman, unaware of his true intentions, finds herself trapped in a web of deceit and forbidden encounters, where her maternal kindness becomes her greatest vulnerability.
