South Korean actor and singer Yoon Seobin is back with a new digital single, "Rizz." This release comes after his 10-month hiatus as a singer since his last single, "Good Morning, Good Night," which was released in December 2023. Ahead of the release, Yoon Seobin has shared various teasers and a tracklist, raising the anticipation of fans who excitedly waited for his comeback as a singer.

"Hello, this is Yoon Seobin. I am thrilled and grateful to release my new digital single with tracks 'Rizz' and 'SQUARE.' Through this promotion, I hope you’ll be able to feel the story I want to express and deliver to you. I have prepared and worked a lot since this is my comeback as a singer after a while, so I ask you to look forward to it with much love. I wish my music and story could be conveyed well for everyone. Thank you," he said.

The single includes two tracks, “Rizz” and “SQUARE.” The lead single, “Rizz,” is a dance track that opens up with a medium-tempo, simple guitar loop along with the artist’s sophisticated vocals. This track is a dedication to everything inspirational to the artist by personifying them as ‘she.’ The music video for “Rizz” was entirely filmed in Los Angeles, California, showcasing the city’s beautiful scenery with the cool, refreshing vibe of the song. The second track, “SQUARE,” is about telling oneself in the mirror, ‘We are now square,’ emphasizing the desire to be free without stressing oneself too much. The track hopes to inspire the listeners to look back and think about life in a clumsy yet serious way with a sentimental guitar sound and soulful vocals.
