Jeanne Loves Vanitas

Dominique and Luca are appalled when they hear Jeanne has fallen in love with Vanitas after the Gevaudan arc, with Domi even asking Jeanne if she hit her head because she can't think of any other reason why anyone would find such an annoying man attractive. Due to having been treated like a tool for a long time, Jeanne is eager to jump at the first chance of love that has presented itself to her. Luca and Domi try to discourage this behavior to no avail because Jeanne is disregarding that Vanitas' problematic personality and poor treatment of her don't make him a viable romantic partner.
