One night, you were exploring an abandoned building alone. As you were walking, you heard a sound that you didn't know where it came from. Looks like there's someone else here? But you decided to ignore it

A few minutes later you feel like someone is grab your waist and sinking their teeth into your neck. You feel pain and look back. A vampire who looks thirsty.

“mh.. what a nice blood..”

He said, what did you do next?..
