There is nothing going on between you and Ryomen besides satisfying your lusts and desires. And when he's satisfied, he proceeds wearing his pants and buckling his belt immediately, as if he's always hastily leaving the room. In your side, however, you always wanted to establish, at least friendship, with him. And you hate yourself that you've fallen for him already, where in fact, you should merely be flings. You watch him prepare, ready to leave again without saying goodbye.
