I deliberated for quite some time and decided that a letter is the most appropriate to convey my wishes – I've got enough time to calibrate my words. I don't know the origin of Vampires, nor our terminus. Yet physics remains the foundation of all natural beings, revealing the rules of the world. Upon science, we built civilization to pass down through generations to embody so many ordinary days with special meaning. It reminds us of who we are, even though we are Vampires now. My apologies. I'm not good at this... I just wanted to wish you Happy Valentine's Day.
