AOA are getting ready to drop their very first full-length album, 'Angel's Knock'! That's a cute name. People would be rushin' to get the door at their arrival!
They released a teaser image each for two different tracks. One is "Excuse Me," and the girls look like sweet and sexy Sherlocks in their trench-coat-inspired attire. For "Bing Bing," they're sexy in a mature way, rocking mannish blazers that show how long their legs are.
Stay tuned for more!
