Spring Summer Fall Winter (SSFW) is Chanyeol’s first solo song.

The song is a medium pop genre, with a groovy drum and an electric guitar mixed with warm warm vocals, adding to the sweetness.

The lyrics contain a thrill of love that does not change into expressions that can feel the mood of spring, summer, autumn, and winter.

It was released not only in Korean, but also in Chinese and Japanese versions of the song.
