So many characters will confused u at first, but the more episodes will bring u to know their growing characters, quite fun movie with many good looking actors and actress.. I acknowledge Kim Ji Won from this movie. I really like her character as Rachel on first several episodes,,but her character didn't get enough space to grow, unfortunately.. And she has cute bangs, kinda reminds me to chiaki kuriyama and Joo Young of After school group, and much cuter than the main role (sorry Eun Sang fans..) The chemistry of the three main roles are quite good. I'm a bit fall in love with Young Do. He could be easily loveable on another teen story with that loner and meddlesome character, but the script is not on his side,,
