>>3187512Apparently, Yoko Taro didn't even want a romance between them. He wanted their relationship to be "parasitic", with Caim being the parasite and Angelus the host. The idea to make them romantic was Takamasa Shiba's idea. And the big deal between them in the second game, Yoko wasn't even involved in.
Also, it seems he doesn't even like Caim. Pity, because I've become very interested in his character.
