My Fake Mommy Is the Real Master

Song Yuwei stands to inherit her family's martial arts school, and her own relatives betray her for it. She loses her memory and people start calling her an idiot. A boy named Fu Xiaobao finds her and tells everyone she is his mother, so she moves into the household as one. The man there, Fu Tingyuan, is supposed to be a cripple who cannot walk, and he is using the disguise while he works on his own revenge. The two of them fight back together. Song Yuwei takes the martial arts hall back. Fu Tingyuan drops the pretense, says who he is and seizes power, and the people who had been against them are beaten. After that the lies between the three of them come apart and they work out what they actually are to each other.
