"Some of my favorite moments from Love Yourself: Speak Yourself The Finale," Liza wrote in an Instagram post, which featured clips from the concert. "This trip and experience have given me a deeper meaning and appreciation of what “fangirling” is.
The actress went on to share her experiences from attending the concert all by herself.
"While waiting in line for many hours out in the cold with nothing to eat and nowhere to sit, I started thinking about my fans and what they have to go through just to get a glimpse of me. Words can never express how grateful I am to each and every one of you. I’m proud to be a fan of such talented people and I’m proud to have fans who are the most loving and understanding people I’ve ever met. I’ve got the best of both worlds."
