Belting out "I like wewe oppa, what should I do" in her hit song, "Good Day," IU quickly rose to the juu of the orodha as the nation's inayofuata younger sister and was adored kwa many uncle fans. However, as she gradually made her way into appearing on variety shows, we were shocked to see that IU was not so child-like as she seemed. For one, IU does not have a cute, high-pitched voice that we all thought she would have. Actually, it's quite deep.
