I'm a Rabbit female, my best 'guy' friend is a Tiger (I'm a Virgo and he's a Scorpio)

To be frank, the Chinese astrology shows that it will not be a god match for you and the male tiger. It should be attributed to the different personality. It seems that you cannot completely open up to each other, which may cause some arguments or misunderstanding. In addition, you appear to ignore each other's positive aspect. For all the things above, as long as you can handle that, maybe your relationship for best friends will get further.
