Park Soo-min

Park Soo-min (박수민), known publicly as Sumin, is the leader and one of the core voices inside STAYC, the six-member group that turned High Up Entertainment from a producer-led startup into a label with a durable frontline act. She debuted with the group on November 12, 2020 through Star to a Young Culture, the release that introduced STAYC's melody-first identity and opened a long run of replay-heavy pop records.

Sumin's value sits in control as much as visibility. STAYC has never sold itself on chaos or trend-chasing. The group works because its members hold a clean, disciplined center, and Sumin is one of the reasons that structure lands. As the catalog grew through WE NEED LOVE, TEENFRESH, and Metamorphic, she stayed central to the lineup that kept High Up's sound legible across each cycle.

That context matters even more in 2026, with junior group UNCHILD now expanding the company roster and keeping STAYC's influence in focus. Sumin's page works best when it reads as part of the wider Black Eyed Pilseung and High Up ecosystem, not as a thin member stub detached from the label machine that built her era.
