In Ou Lan's heart, Baili Mu is the purest man in the world. His soul seems to have been cleansed by snow, just like when he dances on ice in a white costume, his whole being is spotlessly clean.
She always thought that any woman worthy of her brother must be clean, inside and out, pure enough to make one feel extremely comfortable.
Clearly, Jing Sitian is exactly this kind of girl.
Indeed, her brother has a unique taste. He switched through many stunning nurses, but ultimately kept only Jing Sitian, simply because this girl is the cleanest and purest.
Ou Lan is exceptionally pleased with Jing Sitian, just like Baili Mu, she never cares about a friend's background or status. Those are merely worldly concerns, not worth mentioning at all.
In finding both lovers and friends, one should follow the feelings of the soul. Only when souls can come close is it truly important; everything else is not worth caring about.
