This show totally rocks, and more people should watch it. It is the story of how one girl became the soeur, or "little sister" of the person at school whom she admired most. And after she became that person's soeur she has learned about the different relationships that soeurs have, and has seen first hand the roses relationship to their soeurs.
While Yumi, the main character, finds hardships and troubles trying to understand her soeur and the other members of the student council, she becomes glad at the fact that if she is doing something for them, they can become less burdened.
This show is a very compelling drama and is very addictive, and more people should watch it. A very good example of a "Shoujo Drama" type anime.moreless
