How I got around the whole "not wanting to play the other paths" thing was I saved the path I really wanted(Hanako's) for dead last.
That way I got to enjoy the other paths first, and then was blown away by the path I wanted.
However, while I am pretty attached to the girls in this game, I'm not really obsessing over them. In fact, I actually know why I was even able to connect so well with them in the first place.
I was friends with/had crushes on(occurred at the same time.) different girls in high school who were a lot like the Katawa Shoujo girls. Not exactly, mind you, but there were definite parallels there.
I had a crush on a girl who was athletic and sociable like Emi(albeit she was on the school's swim team instead of track team), a girl who was in the student council like Shizune, a girl who was artistic and cuckoo like Rin, a girl who was motherly and kind to all those around her like Lilly, and a girl(actually two girls) that liked to read, but was socially awkward like Hanako.
I could relate to the characters because I had already met them years ago. Of course my interactions with the characters in KS went a lot better than my interactions with those girls, but that goes without saying.
