JYJ's upcoming new album (to be released in the form of a 'music essay') has already sold over 10,000 pre-sale units in just one day. Titled "Their Rooms, Our Story", the album recently became available for pre-sales on the official Interpark site. Their pre-sales record easily ranked them to the '#1 general best seller' category on Interpark's website. The music essay contains the members' handwritten stories about their lives, and will also include ten new self-composed Korean songs. "It's unique because it's easily collectable," said an Interpark representative. Source: Osen via Naver
