one witch two witch rich witch bitch witch (слэш)

Shang Qinghua is going nowhere in life. He's a shitty novelist and a shitty witch of an even shittier coven, unable to muster up even the slightest, most morally grey kinds of spells, let alone anything really dark.
But with the help of an oddly sticky orphan boy and his new, super evil snake familiar (who can shut up about his terrible plot devices any minute now), he's going to win the contest for Mobei-Jun's hand, shore up his coven's reputation and never have to work another day in his life!
...Assuming he doesn't fuck up tremendously and fall head-over-heels for his familiar.
