The prelude to the worldview has begun as the image of J-US Spoiler, the off leader of boy band ONF, suddenly opened.

The posting on the SNS of ONF's WMM on Tuesday contained the information.

J-US spoiler teaser, which was released, is like a fashion film with sensuous English images and text in artworks. It has its own, imperfect, hollow, yet almost like a cross-section of youth, a chic, sensuous mood that blends uncanny, sensuous moods with the impression of an old, faded photograph on a veil.

In addition, the receipt clue teaser, which was released together, stimulates fans' imagination as to what clues might be to the first question teaser that was released earlier on Tuesday.

Attention is focusing on what kind of storytelling each member will connect to the world view that shows ONF's differentiated narrative, which started with Jays.

It was recognized for its unique concept and signature-like MV, unique musical sensibility and solid planning.

Meanwhile, ONF released its third mini-album, "We Must Love," in February this year and gained huge popularity with the title track "We Will Be in Love." The title track "I Will Be in Love" has been on the rise since its release, steadily gaining popularity among various communities as "Aidol Hidden Famous Songs."
