SEOUL: K-pop boy group Enhypen has achieved a double-million seller with its second full-length album, a market tracker said Wednesday. The album, titled "Romance: Untold," sold 2,113,143 copies within five days of its release Friday, according to Hanteo Chart, a leading local album sales tracker. It marks the first time that an Enhypen album has secured double million-seller status in the first week of its release. "Romance: Untold" represents a shift in Enhypen's musical direction, moving from its previous dark and powerful concepts to a brighter, more romantic theme. The album features 10 tracks, led by "XO (Only If You Say Yes)," a romantic pop-genre song expressing a boy's desire to do anything for his love interest if she agrees. The final track -- a multi-language version of the fan song "Highway 1009" in the album -- is available exclusively on the physical album. Source: Yonhap News Agency
