I still don't understand their relationship. he's a little obsessed with Chateau and seems to have a mission linked to her past, but what about her? Why does she allow him to do whatever he wants? Why she cover him? Perhaps because he defeated her at first, but if so he could ask his colleagues for help. Did she feel in debt because he saved her? But this happened later while she is permissive from the start.
Can anyone tell me if i missed something or it will be explained later?
