Frankly I don't care, but the sudden change in girls really confuse the hell outta me. One episode it was Sia then the next episode Rin started liking Asa. The pace and script was poorly done, the only thing that was worth watching was Kaede going psycho and the box cutter. Without Kaede/boxcutter-tan Shuffle wouldn't of worth watching.
All the girls looks decent to me. Personally, Kaede should of been with Rin with all shes done for him, basing on the anime - comparing with the other girls, Rin is a faggot for ignoring Kaede. Also the ending sucks for being anti-climatic.
