I should outline the narrative. Start by establishing Ryan as a Mommy's boy, close to his mother. Maybe they live in a small town to emphasize isolation. The date in the title could be when Ryan meets Keely, setting off a chain of events. The mother, maybe named Sarah, becomes fixated on Keely, believing she's not good enough for Ryan. Her obsession grows, leading to a climax where the toxicity of their relationship is exposed.
