Months ago I found a manga that involved vampires, but i can not find it again! The story goes- A beautiful english girl is poor, and sells flowers. For some reason her brother disappears. A handsome young man sweeps the girl off her feet, but he turns out to be a jerk. He only needs her because she has the ability to sense vampires. Help! 🙁

I think you're looking for Kuro Hakushaku wa Hoshi o Mederu.

I can not express how much I appreciate this! Thank you! !
