Beautiful song. I keep humming the tune

Coming back to this drama OST, I found this version of the 2003 Korean movie "Classic" / <사랑하면 할 수록> OST song "If Love Has its Will' (adaptated by Li Jian ) , same as the He San female2023-04-02 voice2023-04-02 cover (which was released 2023-04-02 ). Sung by Li Jian, it has lyrics in  Chinese  on  screen and pictures from the 2015 Taiping Wheel 《太平轮·彼岸》movie.
