The series has 25 Volumes and had already finished. I remember the end of the story is really nice <3 Koucha Ouji is/was a very famous shoujo series. jeannguyen
The series first released in Japan in 1997 and in my country like almost 10 years ago. Best shoujo I've ever read. You can buy all the volumes on Amazon or Renta manga I think.
How can this be the end?
