Seventeen's Jeonghan and Joshua are debuting as a duo on October 19 — and hyping up the album with a joint Pinterest diary.

Pinterest Jeonghan and Joshua from the boy band Seventeen are debuting as a duo.

To promote their much-hyped album, they've launched a visual diary on Pinterest.

The duo told Business Insider about their chemistry, their music — and their joint mood board.

Jeonghan and Joshua from the mega K-pop boy band Seventeen are offering fans a dream to lose themselves in and a mood board for shopping.

The two vocalists are debuting as a much-hyped unit, a spinoff of the 13-member band's activities.

As of Monday, they'll be working under the name JxJ — releasing their album, "DREAMSCAPE," and hitting the road together for a concert tour in six Asian cities.

In the meantime, they've been populating not only their Instagrams, but also a sprawling visual diary on their joint Pinterest account.

It's an interesting choice, as far as K-pop goes — usually, teasers are limited to platforms like YouTube or the K-pop-centric social network, Weverse.

In a written interview with Business Insider, the duo described their interest in Pinterest as a means of introducing the "visual world," concept, and vibe of "DREAMSCAPE." The mood boards and the buffet of photos they've posted for fans to feast on are also a "little gift" to their audience.

"JxJ Diary is a space we created to share the concept and vibe of the album more directly with fans before its release.

We spent a lot of time thinking about what kind of content they would enjoy, and decided to launch our first-ever Pinterest channel featuring different sides of ourselves," the duo said.

The singers said they wanted to explore the concept of "dreams" with the posts on their joint account.

They've curated a collection of photographs and behind-the-scenes moments, including everything from candid shots to sneak peeks of their album photoshoots.
