I watched this anime as a child during the early 2000 and I was obsessed with it. The aesthetic, the love story and dramas... It was delightful. I had never read the manga until now, as an adult. I must say that the manga is very different from the anime, but I kinda liked it better. The nostalgic memories of the anime are very dear to me, but as a more matured reader I am satisfied with the story and the character development on the manga. The relationship of Miki and Yuu is very sweet, and despite the time in which it was written and the obvious presence of sexist stereotypes, I felt like Yuu wasn't such a possesive and manipulative male protagonist as you would expect from the genre. He was very respectful and you could tell that he really liked and loved Miki for who she was. And the same way around. I really liked their relationship, and the love triangles that appeared so much on the show weren't too melodramatic on the manga.
The only thing that truly disgusted me was Meiko and Namura sensei's relationship. Ugh. So pedophilic.
