About the Song

《I Know》 is a reflective meditation on understanding and acceptance, built on maturity and the kind of clarity that only comes with time. Released in 2024 as part of SUPER JUNIOR‘s twelfth album Super Junior25 under Label SJ, the track was composed and arranged by KANGTA with lyrics by PIT300, blending seasoned artistry with introspective depth. It’s not about discovery or surprise—it’s about finally seeing things as they are and being okay with it. There’s a quiet strength in that realization, a sense of peace that doesn’t need to shout. 《I Know》 shows SUPER JUNIOR in their element as veterans who’ve lived through enough to know what matters, delivering wisdom without preaching.
