If you liked the Full Moon o Sagashite manga, the Anime-Planet community thinks you'd like:
Ayu, a seventeen-year-old high school student, lives every day without purpose and no hope for her future. She sells herself to men without thinking of the consequences; she doesn't feel pain, sorrow, or happiness; and she has no desire to feel anything at all. To Ayu the world is just a dirty, horrid place revolving around sex and money - until a chance encounter with a kind old woman begins to change her mind. With this woman's help, will Ayu ever find a reason to live?
These manga are very different in many ways, but on the surface they are quite similar. Both female protagonists struggle for survial. Their motivation to continue living stems from their love. While Full Moon takes a lighter approach to the subject, there is still a level of direness to the situation. Full Moon provides comedy and shojo love. Deep Love, on the other hand, takes you to the core of hopelessness. The story is simultaneously upsetting and endlessly provoking.
Chiyuki is a young girl with a terminal disease. Near death, she meets a vampire named Touya and blackmails him into spending time with her; however, he doesn't drink blood because if he took a blood partner the partner would die long before him and he doesn't want to get hurt. When Chiyuki is dying he saves her life by having her drink some of his blood, because he feels even being with her for a little longer will be enough. She returns to school and forces Touya to join her there, where they discover that one of their classmates is a werewolf who is ashamed of being a monster. Both of them slowly become closer to Chiyuki because of her warmth, her will to live, and her non-judgmental love which heals the wounds from their pasts.
