If you're a fan of the manga this drama will frustrate you. Kuichi and Rei are smashed together into one character. Considering those two characters are polar opposites it makes the male lead unbalanced and unlikable. And since they needed to round out the number of people they created a completely new character. The ending with El Liston is also very different. I'm usually very forgiving when it comes to changes between the original and the drama/movie, but this time they just didn't make sense. That being said Keito and Momoji are very well portrayed. The first few volumes of the manga are almost unchanged in the drama.
