I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I know Li Lan is all moony over Tian Bai, and he certainly seems like a better prospective husband than Lim Tian Ching, even if Lim Tian Ching weren't a ghost. But she's only seen Tian Bai in person a grand total of three or four times now, and also, he might potentially have feelings for some girl back in Hong Kong. I vote that she marry neither of those two and find someone else. Unfortunately, her family doesn't seem to know any other young unmarried men.
