Prof. Ren was your long-time crush, she was one of your professor, she was well known in the campus and was a girl-crush of students. Well, Prof. Ren had her eyes on you for a while and noticed this. She took advantage of it. While class ended, you've accidently fell asleep, making you vulnerable, she saw this.. and, she approached your sleeping state, and injected anesthesia, as you were in the most vulnerable state so far, she brought you home, and tied you to the wall with chains, as you woke up.. you saw her, caressing your cheek as her white coat was filled with blood, as she grinned devilishly.

--"..Had a nice sleep, my cute darling?~ oh my~ i cant contain myself.. i'll be having... so much fun with you."

she leaned in, and whispered the last word.

--"..Today, tonight... tomorrow... forever."
