Asia, even nowadays, is still considered an exotic and mystical part of the world for many Western men. Different cultures come together there, which, at first glance, appear to be beautiful and alien at the same time. Incidentally, this applies not only to culture - but also to Asian women. They combine many positive characteristics such as friendliness, self-discipline, grace, and good-lookingness.
And, this apparent difference is obviously something that attracts Western guys. But, at the same time, it is also the point that creates the contrast in relationships with your local and Oriental beauties.
