[Anime Crossover] The Black King's Dark Past

After a whole string of embarrassing misadventures, Sikong Yao decided that he had used up all his luck before the age of fourteen. All he had done was win a free trip to Japan by chance. But then he got dragged into a daring mission to win over a bunch of guys. Not only was he forced to switch from straight to gay, but after finally winning over all the male leads, he replaced their memories and was ready to take off without a backward glance. Then the Dresden Slate descended from the sky and chose him as the Black King. And then the memories of everyone he had won over came back. Faced with a huge wave of ex-boyfriends rushing at him, Sikong Yao was branded a scummy top. And now the Green Queen, his yandere childhood friend who could not be cured, was coming to kill him from the Other Side... Just thinking about it is enough to make him... feel a deep, soul-crushing emptiness.
