For some background info, I am a 16 year old male. A friend of mine is rapidly losing my respect for the way he treats women, many of which are also my friends. I also have a crush on his current girlfriend, and I know he is mistreating her. Can I use the shogun method to show her that he is not for her and that she should go out with me, I know I'd treat her better than he does and I'd get myself a beautiful girlfriend in the process. If I should not use the shogun method, are there other methods I could use for everyone's benefit?
