JOD is one of my fave MV's and songs as well, and suga's rapping was legit the best thing lol.
I loved it a lot for the piano also~
also idk if you guys ever realized but there's a short piano sequence in "First Love", I think at around like 0:48, and it sounds lowkey like the piano sequence in Just one Day, plus first love has the clock ticking noise, and there was a huge clock thingy in Just One Day. I mean it's probs just me trying to create non-existent connections, but still, I've always loved that small connection even if it was just a coincidence.
