你不知道的事 Things that you don't know

Its a song dedicated by Wang Lee Hom a Taiwan celebrity.
This song is full with lyrics that will touch those couple that just broke up.
It can also be a song that a sweet couple would love it.
This song is meaningful and filled with love and feelings of passionate inside.
I guess the way this guy wrote a song is through his mood and feelings.
Though the lyrics are partly about leaving a person but what I think is loving.
