just don't kill Charlotte to make our little snake strong

I love the over all development of the story but hate the harem stories I mean it's always painful for the second n third lead they know the person is with someone else is it necessary to develop feeling for them specifically this gu guy he know how much devoted his master is towards the girl but he is thinking how to be with her and not let them meet. I don't know why but I hate novels with harem theme
