Denise Deng is said to be director Ye Nianchen's "exclusive actress", but this time the male protagonist is not Aaron Kwok but instead, Justin Lo. In the story of "Silence Speaks Louder Than Words", Justin Lo plays a house singer while Denise Deng plays a florist with hearing and intellectual disabilities, and an affair occurs between the two. Denise Deng frankly stated that this is her first time playing a character with hearing and intellectual disabilities, which for her is a great breakthrough. She admitted that she had no real concept of "hearing impairment" before shooting the movie. She also spent a lot of time understanding the conditions of hearing-impaired people before filming. "This is something very fresh to me, and also a great challenge".
