I'll cut the chit-chat with a short filled question; could you kiss close on some girl you've met before and have known for a long time? No, I'm not stupid and saying I'm gonna kiss my best friend (who's name is Eden). I'm asking if I should kiss close her after I get the three IOI's and know that she's attracted. The only reason I'm asking this is if people have had experience where they get the LJBF speech.
A heads up, girls who are your friends by definition will give you IOIs because they are your friend ergo they have interest in you. Mystery's whole 3 IOI thing, in fact his method is designed for women you haven't met before on a cold approach.
Obviously it's possible but what's the point in risking a friendship when there are thousands of suitable girls in your proximity who are not your friends.
