A 9/10 femcel cannot easily be changed to be a better person.
There is no cause of the reason she rejects everyone. You cannot fix something that has no apparent cause.
When you stop and think about her, you realize she can easily have sex with any woman or man she pleases in 2 minutes, so where is the story of her life? There is no cause why she is so haughty to everyone. There is no sad story about a man who cannot find love. Thus she cannot be easily fixed to be more amiable. The likely cure is by dna modification of the person.
