Loneliness Society (2023)

When courier Meena witnesses Athit struck down in the road, she rushes him to a hospital. There, she's put in a position where she has to lie to the staff about her relationship with the patient. When his family arrives to find Meena caring for him and Athit awakes with no memory of his relationship with Meena, his family readily attributes it to amnesia. His younger brother Than is less convinced.
