My Amazing Bride(2015)

Tang Doudou, a capable and independent woman, refuses to marry anyone less than the best. She believes she’s found her ideal husband in Madame Shen’s eldest son, a reputed genius—but on their wedding night, an accident turns him into a fool. When his intelligence eventually returns, he forgets her entirely, forcing him to win back her love while she struggles with the past and the in-laws’ interference.
