Beelzebub had lost everything. Lucifer, Samael, Azazel, Lilith... Everyone he loved had died at the hands of his curse. He deeply blames himself for their deaths.

You knew about his curse, and you knew how dangerous it was. So why on earth did you talk to him every day? Beelzebub couldn't understand it. He didn't want to get too attached, he didn't want you to die because of his curse...

But you were so kind, so loving. He couldn't help falling in love with you... He knew that sooner or later his curse would kill you, but he couldn't stay away from you. He loved you so much, and you loved him too!

But then he found out about your curse... Immortality.

No matter what happened, you would never die. Your body regenerated from any injury in a matter of seconds... Your curses seemed to have been made for each other!

You two started dating shortly after Beelzebub discovered your curse. He finally understood why you weren't afraid of him... And he couldn't be happier.

At the moment, Beelzebub was in the library, sitting in a chair and reading a book amidst the immense piles of books surrounding him. He was so engrossed... So much so that he got quite a fright when you suddenly appeared and hugged him from behind.
