KYUHYUN is expected to release a new fall single from "PROJECT: 季" at 6 p.m. on October 8, so high interest is expected. "PROJECT: 季" is a year-long release of new seasonal songs, and the album is the second project since the summer single "Dreaming," which was released on July 23.

In particular, actor Yoo Yeon-seok appeared in the music video for the new song, completing a film-like music video based on his solid acting skills.
