Seoyoon Lee (이서윤) has been competing for 4 years. Her best event is the 3×3: a personal-best single of 8.16, set at Cube Camp in Jeju 2026, puts her in the top 3.1% of the 288,433 people who have ever been ranked in the event, and 195th in Republic of Korea.

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
