I did not read the manga this drama is based on (I didn't know there was a manga until I read other people's reviews), so I can't tell you how good or bad of an adaptation it is. But as a viewer who has not read the manga and was experiencing the story for the first time, I thought this drama was superb, very heartwarming and sweet. (I also loved that there was a Lolita character, as I also wear Lolita.)

If you read and loved the manga, you will probably agree with the other reviewers. If you have not read the manga, then I suggest giving this drama a chance. I think you'll find yourself liking it.
