The next time you're feelin' blue, just remember a pair of squeaky shoes will getcha through. Or maybe just watch this video.
The clip features a little tot named Yeseo, who's famous -- along with her sister, Yerin -- for being ridiculously adorable. She starts off the video with her grumpy face on, but when she starts squeaking around in her adorable shoes, she just can't stay mad.
Really, though. Can anyone stay annoyed after watching this?
