My dearest Elena...
Our relationship was never easy. You are still human, while I'm a vampire. I never wanted to hurt you, because I love you, but sometimes I've done it and I'll never forgive me for this, even you did this sacrifice to make me happy. My life without you is like en eternal night, I can't live without you, you're the most precious thing I ever had. I'd like to stay with you forever, to love you and protect you from this evil world. I could even give up my immortality live just to live with you, make you happy and see you smiling every single day, because your smile is like the shinny sky in summer. But destiny is also cruel and it was always cruel with both of us. Your life is made of losses of the people you loved the most. My life is damned just like me. I killed a lot of innocence people just for my irrational need of blood, I saw them suffer, I was and I still am a monster. So I must leave you. I have to do this to save my brother from certainty death. Oh, yes, my dear Elena, you don't know this, because he ordered me not to talk with you about this. He was bite by a werewolf and this bite could kill him, even he's a vampire! So I have to go and find a cure. It won't be easy, I know, nor for me nor for you. But remember, my little angel...I will always love you...never forget me even I'll die in this mission. You will be in my heart, the hope which will guide me in this long adventure, the light in the dark. Maybe one day we'll be together again, but for now nothing's certain and I don't want to make promises that soon I could break.
I love you, sweetheart.
