Jeanne can't understand why her heart can't stop racing, even though she loathes Vanitas. Seeing how careful and carrying Vanitas is, she wonders where his selfishness and egotism went. Vanitas asks her where she wants to go and Jeanne explains she wants to see Paris. While it isn't her first time here, she is usually protecting Luca and can't enjoy the view. Vanitas then takes her around Paris, showing her various locations. Dominique and Dante are following them, but as it turns into a regular looking date, Dante is bored and wish to leave, but Dominique states he came this far off and needs to stay until the end.

Noé tells Ruthven that while he speaks with him, it reminds him of his teacher, like if he was attending class or simply enjoying it. Ruthven reveals that long ago he was a teacher of sorts. Many of his students adored him and gathered by his side. He wanted they join him and create a brighter future, but now they are all dead. If he had now students like Noé, he would have joyful days, but is concerned that someone could appear who would take advantage of his kindness. Noé guesses he means Vanitas, but states he won't do that and while he would use anyone, he can't stand seeing anyone getting hurt because of him. Noé was annoyed when Vanitas told him that humans and vampires are the same and that they are both selfish creatures, but at the same time felt his loneliness. Ruthven then wonders what Noé thinks of humans and vampires.

As Vanitas went to the toilet, Jeanne decides to practice what she will tell him. She starts saying that she enjoyed herself today and that she started to love him, but then feels quite embarrassed. In that moment Vanitas appears behind her and tells her he loves her too, shocking her. As Vanitas is enjoying it, Jeanne tells him he got the wrong impression and must look at her with contempt, like she is a maggot. He wonders what she means or if its her fetish. A kid then trips next to her and injures his leg. Seeing his blood, Jeanne loses herself and is about to attack him, but Vanitas puts his hand in her mouth and stops her. As other sees she is a vampire, Dante puts a smokescreen and help them escape.
