HY - “In Love” (Theme song for the film ‘366 Days’) Music Video

Even if you weren’t the one they chose, the fact that you loved doesn’t change… A bittersweet yet forward-looking sentiment runs through this touching HY ballad.

Written as the theme song for the film “366 Days,” released in January 2025, the track is positioned as an answer song to their 2008 classic “366 Days.” It beautifully portrays emotional growth—rising from the pain of heartbreak and embracing even that experience as a cherished memory—and is also included on the album “TIME.” Set across Okinawa and Tokyo, the film unfolds a pure love story spanning 20 years, and this song superbly captures its worldview.

For those who have reached the end of a romance, or who are about to take a new step forward, this is a song that will gently give you a push.

It’s a song that gently stays by the side of anyone caught in the midst of a tender, aching romance—overflowing with feelings yet unable to take that crucial step forward.
