+I recommend reading Pandora Hearts as well, especially vol.22 because it connects with Vanitas.
(In case you didn't know, Pandora Hearts is a parallel world and there are many items from the PH world hidden in the Vanitas series)
+You don't expect romance. If you don't want to get hurt because of mochizuki Jun is known as "She's a Ships breaker," so don't expect canon ships from her.
+Mochizuki Jun is LGBT+ and likes to read all genres: mxm, mxf, yuri.
(Note: Mochizuki is LGBT+ in guidebook vol.18.5)
+There are some characters who are bisexual and when Mochizuki writes LGBT+ characters, she doesn't have explicit moments, such as Elliot (Pandora Hearts), who later reveals he's gay. which is based on guidebook 18.5 orYou must have information about literature. which it references important information and hints at Mochizuki that her character is LGBT+.
+Mochizuki ships include vanoé and vanijeanne as well as dominoé.
(You can read information about Mochizuki ship vanijeanne and dominoé in the vanijeanne&dominoé article on the fandom wiki and Kikan magazine.)
