Sungkyu (성규)

When INFINITE took shape as one of Woolim Entertainment's signature acts in the early 2010s, Kim Sung-kyu — performing as Sungkyu — established himself as the group's lead voice, a role that would eventually carry him into a parallel solo career beginning in 2012. That dual presence, as a working member of an active group and as a solo artist with his own discography and touring life, defines where he stands today.

From group stage to solo debut

Sungkyu's first move as a solo act came in 2012 with the extended play Another Me, a release that signaled an appetite for work beyond the INFINITE framework without breaking from it. Three years later, 27 arrived as a second EP, the title nodding to his age at the time — a choice that gave the record a quietly personal register. Both releases established a pattern: solo output that ran alongside, rather than in competition with, his commitments to INFINITE.

Music & Discography

The 2020 EP Inside Me marked a more considered phase of his solo output, and the following year produced "Won't Forget You," a single that has since settled into his representative work — the title most consistently cited when his solo catalog is discussed. His live setlists suggest a range that extends further: tracks such as "41 Day," "Fade," and "Because" have featured prominently in his recent concert performances, sketching a body of work broader than his formal release count alone might suggest.

In early 2026, Sungkyu was preparing to release Off the Map, a project he described in terms of inner depth and personal disclosure. Pre-release imagery in a quiet black-and-white visual language set the tone ahead of a March arrival. The project was framed as the completion of something — a final piece fitted into place — though the material does not specify what larger sequence it concluded.

Touring & Live Activity

The practical measure of Sungkyu's standing as a solo act is his ability to sustain dedicated touring. His Asia tour, titled LV4: Leap to Vector, reached the Broadway Theatre in Macau in April 2026, where a diverse setlist drew a capacity response. The tour underlines a consistent live presence that has developed across multiple markets.

That commitment to performance has not been without cost. In early 2026 Sungkyu disclosed that he had performed through a fracture injury, continuing to take the stage while the bone was still healing — a detail he surfaced himself during a segment of the program Thursday Night. The admission generated significant attention less because it was unusual for the industry than because it was stated plainly, without the framing of triumph that such disclosures often receive.

Standing

Sungkyu occupies a position that a number of first-generation idol vocalists have navigated with varying success: maintaining relevance as a solo performer while remaining an active member of the group that first established him. His discography is modest in volume but consistent in intention, and his touring activity suggests an audience that follows the solo work on its own terms. The Off the Map project, arriving in 2026, represents his most recent attempt to deepen that solo identity.
