Thai serialized version of the Sandra Bullock film "While You Were Sleeping"
When delivery girl 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. Athit's family overhears the fib and when Athit awakes with no memory of Meena, his family readily attributes it to amnesia. His younger brother Tun is less convinced.
