This manga is worth reading in my opinion.

I liked the art and was very consistent, however this manga doesn't draw a line betwen its "sweet" and obscure charge, it is a mess of emotions that builds slowly so the first chapters to the ones in the middle aren't as enjoyable to read but its climax at the end resolve much of the conflict you might have while reading trying to understand what is going on and gives more sense to the extreme characterization of the main characters, specially Sakura who seems unrealistic and obscure to an extreme.

There were some plot cards used that made no sense and had no resolving like the whole Niijima and his girlfriend revealing they knew information about the missing twin's whereabouts, conceiling then the information and never bringing it up again.
Therefore in my opinion, most of the secondary characters felt forced into the story and the plot, which shows the lack of effort put into the story.

Even though side characters and story isn't the best out of this manga, the two main characters and their development throughout the story compensate its weak points.
The art was pretty good and it definetly is worth a reading.
