The song is a remake of 'By Myself' (나 혼자서) from the SBS drama Ja Myung Go which Girl's Generation member Tiffany sang back in 2009.

Zhang Liyin had mentioned that the song is a follow-up track and a continuation of the storyline of Agape during her YouTube Interview with Victoria and Tao.

He goes to the places with memories of his parents and sees flashbacks of their love story (the scenes in black and white).

She met Tao’s father when she got off the ferry at the harbor in Incheon when he picked up the piece of paper with the address of her destination and gave back to her.

In the end, after Tao saves a family from a fire, Vic, who has been worried to him, rushes to hug him.
