Melly doesn't really hate Mariana!! With Arman being her creator, she naturally feels the need to protect him, even though she's no longer head over heels in love with him so to speak.<br/><br/>Yes, there's a bit of jealousy when it comes to his attention. But unless you do something that shows you intend to do mental/physical harm to either of them, then she's fine.<br/><br/>Maybe since she feels that way, Melly and Mariana haven't done much to further their relationship. Hopefully that'll change as the story progresses!
