It's a weird question because that is how I amuse myself and jump to an answer that may not be true, because I am a suspicious paranoid who thinks he can solve problems with premature conjecture.
Spoiler I'm now at act 4 and female Kim nearly revealed romantic feelings.
So to ask why bother gives me the opportunity to answer.
1 Because the default bothers me and the question nags me
2 Because this is the default female Kim: http://images3.wikia.nocookie.net/__cb20101219211454/nehrim/images/5/50/Kimfemale2.jpg
I will use an upload post in the Nehrim and Mods topic.
