Oh and I'm so curious about what happened to Jung In! Did she die...? Or did she become a vampire? O.O Because…
To answer Your questions: Jung In became a vampire. Do you remember when Prosecutor Min bit hs friend doctor Ra Jae Wook but he survived without even becoming a vampire? Then The bad boy vampire (the sexy vampire as you call him) has already bitted Park Hoon (the one that turned Prosecutor Min into a vampire) and made him a vampire.
The options to become a vampire in this drama: Be the first victim of a vampire or a vampire shares his blood with you, in the doctor's case he became a vampire because that bad boy vampire shared his blood with him as for Jung In, either Prosecutor Min shared his blood with her or literally bitted her since his first victim wasn't Ra Jae Wook (he didn't turn into a vampire after being bitted by Min). Either ways; she became a vampire.
I hope I answered your questions even though it's a bit long.
Hana Kimi 2007 was one of the three dramas that got me addicted so it's the best no matter what!
To The Beautiful You was a disaster: I dropped it ever since the first episodes.
