^OMG That is the sweetest Ayu related thing I ever heard!
Idk if this sweet but more like funny, back in my highschool days we're tasked to present our class' very own aerobics. My friends, knowing that I listen to Ayu a lot (it was (m)u~Secret era) thought that I could help made one of the sessions. At first I was reluctant because I'm afraid people would not understand but I made it in the end. I chose AUDIENCE and incorporated the CDL 04~05 choreography in it
Sometimes in the dorm I was living, some of my close friends can be heard humming to Beautiful Fighters lol I swear they're the manliest guys I know but they hum to the "It's fire womaa~n" thing
