Ef is split into three stories, running simultaneous to each other. Two of them pretty much completely overlap each other (Hiro and Kyosuke) while the other is kinda in it's own little world (Renji).
This anime rly appealed because I seriously love watching romance anime where the heroine has some kinda 'flaw'. Chihiro's memory defect was original and Miyako's 'no one cares about me' was pretty good too. My only critisim is Chihiro's seiyu, which was kinda a turn-off. Overall, it's one of the best roamnce i've seen for a while.
