I've put the romanisation of the song's lyrics under the cut. I did the romanisation myself because I can.

Reading and wiriting in hangul is pretty easy. As crazy as I am, I bought a korean language book a few months ago.
Still, I hope it's correct, but I'm pretty sure it is because I checked it a few times by comparing it to their singing.
