The song does not follow the familiar motif of initial vibrations, but focuses on a more mature perspective: love as a long-term companion choice.
After two chapters with 5 MVs, the Dinh Music project enters the closing stage with the message "New Visual New Me" - a journey to refresh the image and musical storytelling of Phan Dinh Tung. However, "Thanh doi" does not bring a sense of ending, but is like a transition, where the male singer aims for sustainable values of emotions and relationships.
The song is composed by musician Vu Ngoc Bich, with a modern music color with a mixture of Deep House and Festival Progressive Anthem. The arrangement creates a youthful feeling but still retains the familiar warmth in Phan Dinh Tung's voice. The restrained, experienced expression makes the lyrics sound like a carefully thought promise, instead of a momentary outburst.


Unlike Valentine's songs that often emphasize the romance of the beginning, "Thanh Doi" talks about the prospect of going together for a long time. The central theme of the song is the desire to be attached - love not only for the present but for the years ahead. This approach helps the song expand the audience, from young people in love to couples who have thought about marriage.
The MV is directed by Kien Ung, using metaphorical images to expand the meaning of the story. The character of the bride is different among the same crowd, creating a feeling of being lost, thereby highlighting the message: love is not in complete integration, but in finding someone with the same emotional rhythm. The storytelling in images helps the content of the song become clear and deep.
