He is a vampire. Vampires are immortal, but humans are not.
I am willing to endure 200 years of pain just to stay with you for a few more years, but do you know? When you marry the woman you love, the pain is more painful than my 200 years of pain.
I really can't wait for your sixth life. Even though you are so cruel to me, I will kill your beloved at all costs, so that you will always remember me in your heart.
It's a pity that I can't see you in your sixth life. I can't let you hurt me anymore. This is probably my punishment. . .
