I thought that this manga had all of the right things to make it one of the greats. The drama of this high school girl, Yaya, who has another personality inside her, named Nana. The story was very well put together, and portrayed the life of a teenage girl who does not know who she is, and struggles through it. This manga I recommend for people to read. It's very entertaining and heart wrenching. The art isn't the greatest, but once you get past that, you will fall in love with it.
