f(x) - 4 Walls MV Reaction

Love this song so much. I couldn’t help but focus more on the song and hopefully I can figure out what actually happened in the mv lol. I am glad that they are back! :D Thanks for watching! -Please excuse the random sound when the mv ends. -__- Go watch the video here: Subscribe!: My 2nd Channel (VLOGS): Twitter: Instagram: Kpop Amino:
