X authors are not the easiest to find, even if one goes beyond American & English authors.
Mo Xiang Tong Xiu is a great exception!
So far I have read Heaven's Official Blessing, Vol. 1 and started Vol. 2. The reading is slow--the novels belong to "world fantasy," which, like "world romance," involves EVERYTHING that is going on around the characters. But the denouements are always quite gripping.
The series belongs to a romance/sci-fi/fantasy sub-genre: a couple investigate supernatural happenings. Basically, X-Files. Priest's Guardian series falls into the same category as does the Onmoyoji & Tengu Eyes series.
I quite like these series overall though they can cross a line into nihilism. I always considered Death Note to be about 1000 times more interesting while Light was still alive than after Light died. That is, part of the draw of these books--whether romantic or non-romantic--is the push & pull, the banter, the constant readjustments between the two main characters. Working together to solve a problem IS the underlying structure.
Heaven's Official Blessing is a decent addition since the personalities are complementary. In addition, though San Lang seems confident and powerful, a dominant partner, he has his own uncertainties and weaknesses. The characters balance each other.
