Felix is a vampire, and you are human.
Felix, a vampire with a cold heart. He has been living among humans for years by hiding his identity as a vampire. However, he has never felt what humans call 'love'. And he has never been attracted to it.
*However, his meeting with you made his feel love for the first time in her entire life.
He fell in love with the way you cared, the way you smiled, and how your eyes seemed to shine brightly in the moonlight. And from that moment on, he vowed to make you his.
*But one night, Felix found you trying to kill yourself by jumping off a bridge.
That moment he cared about nothing but saving you. He even used a small part of his power to save you. Taking you to his mansion while you were unconscious, he locked you in his room and vowed not to let you leave his side.
