Korea University festival — joint stage with LE SSERAFIM
2026 Korea University Seoktap Daedongje (KULIMAX) · Korea University · Seoul
The university's spring festival ran 19–21 May with LE SSERAFIM, CORTIS, TOMORROW X TOGETHER, BOYNEXTDOOR and fromis_9 among the acts. ILLIT played the first day and closed with a surprise joint stage with label seniors LE SSERAFIM, mashing "It's Me" into "CELEBRATION". The organiser did not publish a day-by-day line-up; the first-day date follows the group's own channel and its dated posts.
