the vibe of this song is kinda similar to Cherry Bullet's Love So Sweet but with heavier instrumentation. LSS is lowkey & cheery. ASAP is also lowkey but like you said, at the same time upbeat. sieun looks so good with orange hair😫 her vocal tone stood out to me. idk if you have reacted to f(x)'s nu abo but seeun's hime cut with dyed tips gives me major flashbacks to krystal's legendary hair from that era
Blue tips Seeun (Say-eun) was the super smiley one from So Bad. Isa was the one you couldn't stop talking about in So Bad and here she follows up Seeun at 2:10.
