This bring back memories. GF was my first yuri and my awakening to yuri (in more ways than one). At first I thought that this was about friendship... Oh how wrong I was and I'm glad I was wrong. GF might not have been the best yuri story there is but -- without a doubt -- It's my favorite. AkkoMari will always have a special place in my heart.
On another note, the great Morinaga-sensei's art has improved yet again! I hope I can read more of her works.
