I loved J Soul Brothers ever since they released Japanese Soul Brothers. A fun fact: this is the second J Soul Brothers group (there was once a group with 14 members, but they’re now called EXILE) and they started off as background dancers and then later formed a group with the help of Hiro, the leader of EXILE/J Soul Brothers
Refrain is a Pop/R&B track with gloomy and dark visuals. The guys sing and dance with sincerity as rain pours outside of their window, reflecting on what I think to be a past relationship. It may sound depressing, but it’s actually really nice. Enjoy.
