52 Hz represents a frequency that no one of the same kind can receive, which means "I love you, lonely person". Loneliness is the beginning of all love stories... In a crowded city, there are all kinds of lonely people, young men and women who don't have the courage to try the taste of love, long-term lovers suffering from economic pressure, middle-aged singles bound by the secular world, same-sex couples who love each other but are not recognized... "52 Hz I Love You" describes that on this day when the whole world celebrates love, it is finally the turn of those who long for love to play the leading role and compose a romantic and sweet love song.
