Rainbow's Jaekyung turned into one of thousands of fangirls at the g.o.d reunion concert!

"I'm the happiest girl in the world," she posted earlier today. "g.o.d's music was by my side during my puberty.... even now, whenever I listen to g.o.d's music, I'm taken back to the old days and my heart cries! In the past and present, thank you for giving me so much joy!!!!"

We're glad she was able to tap into her nostalgic side and re-live her childhood! Is there anything you're nostalgic about?
