Characters
The main character is Sawako, an average high school girl bullied to the point that she drops out of school. Other important characters are her parents - her father who supports her in whatever she wishes to do, and her mother who desperately wants her to finish her education. The other characters are her bullying classmates and her friends turned enemies. This manga really focuses on Sawako alone and her own strength.

Drawing Style
Shoujo manga = shoujo style. The style is sketchy and typical of Keiko Suenobu if you're familiar with her work.

Enjoyment
This is an enjoyable short series (one volume) It deals with teenage relationships and bullying in schools, but shows how Suwako deals with this with the help of her parents. The ending is happy and Suwako fights back against her bullies at the end.

Overall
A shoujo manga well worth reading. The art is pretty and overall, this manga ends in an uplifting tone.
