Boy Makes Girl (2023)

When his mother passes, a software programmer on the autism spectrum, Aaron, struggles to cope with the change. He builds a lifelike version of his childhood therapist Emma and tends to his mother's last nursing client -- a bitter old man named Ben. As his connection with Ben grows and Emma's socialization pushes him beyond his own social abilities, Aaron must learn to adapt and change in life for the first time.
