It's a fic that combines Conan and The Prince of Tennis!
There are two male protagonists, GIN in Conan and Yukimura Seiichi in Net King.
Feng is the stepmother. She never shows mercy when she abuses the male protagonist, and she is cruel when she abuses the female protagonist. ! !
Feng is a beauty-controller, but because he can't control it, he integrates other anime characters into it, and then turns it into a harmonious comprehensive comic, oh ho ho ho! ! !
