This is IU’s first performance of The Story Only I Didn’t Know. It’s also the best, and most emotional, so far in my opinion.

She performed a short version of Good Day earlier in the show and the contrast between the songs makes The Story Only I Didn’t Know even sadder. I felt like crying the first time I watched it (which was also the first time I heard the song).
