It was just one year ago since 7 SINS debut in Japan at “Seol Train Nine Muses & Friend”. Since then the ladies have been working hard releasing four singles out through the year, as well as recording the RSM’s first collaborative digital single, “Shooting Star” with ASI and D.I.V.A. So it comes to be a surprise when leader, Sadie Hwang, released her first solo digital single - LOVE HURTS ft. Japanese rapper Coma-Chi - First in Japan before it made it’s way to South Korea. What caught our attention was that the song is in English; Only Coma-Chi’s parts are in Japanese. RSM Management Released that a mini-album is also in the works.
