My Vampire Professor

Upon discovering my boyfriend in an intimate moment with his "childhood friend," I sought solace in a local bar, where my dear friend surprisingly arranged a professional companion for me. This individual turned out to be exceptionally talented and unbelievably attractive. With a hasty departure the next morning, I left behind some cash without looking back. Later, fate led me to bump into this "call boy" in our very own classroom, revealing a shocking truth – he was none other than my new professor. As time passed, I gradually became aware of an unusual aura surrounding him. "You've forgotten something," he nonchalantly said, handing me a grocery bag in front of everyone, maintaining a straight face. Startled, I started to ask, "What—", but he had already walked away, leaving the rest of the class staring at me, curious about the contents. Peeking inside, my heart sank as I recognized the bra and the cash I had left at his place, now resting in the bag.
