Yoona lives with her 8 best friends, which are more like sisters. She lives to see them happy, even though they sometimes disagree in things. For example, they think that she should ditch her best friends Changmin and Kyuhyun, since they are immature and a bad influence on her; however, they know that she is happy with them so they let her be. And the fact that they are all in love with love is sickening to her but she knows it's what makes them happy so she supports them. She wants them to be happy so she will do anything for them... even if it means that she has to face the nightmare she thought was long gone.
