Move over Taylor Swift's "22," IU is now here with an MV teaser for a new song, "Twenty-three."

However, she doesn't seem all that excited about it... perhaps she's feeling the quarter-life crisis already.  In the short teaser, that barely shows even a second of the track, a lovely IU walks to a table with a cake that has candles in the shape of her age, 23.  She then seems awestruck by the taste of the cake before sighing in defeat and planting her face into the cake instead of eating it, making all cake lovers gasp.

Check it out above!
