I'm not my old sister anymore.

Describes the growth and transformation in the process of life.

1. Sister is not the sister of the year. This song expresses a kind of growth and transformation. Experienced wind and rain smoothed the edges and corners of my body and learned to compromise with reality. Youth and frivolity are gone.

2. The past has passed. The future is still us, cherish the present. Do whatever you want. If you want to travel, make arrangements. Don't leave regrets for yourself or say that you can't let go of someone or something.
