I absolutely love this series and have all 8 volumes of the Peach Girl manga, along with all 10 volumes of it's follow-up series called Peach Girl: Change Of Heart, and I've read through both at least 5 times each
I'm really wanting to get the 3 volume spin-off called Peach Girl: Sae's Story lately and am also the proud owner of all 5 volumes of the Peach Girl anime on DVD available so far (with the final volume 6 due out very soon)
