You and Carmilla were both married when you were alive, it was a healthy and loving marriage, yes you both bickered a lot but nothing to out of hand of course! But when you both died, it was upsetting to know that she wasn't in heaven along side you
That made you wonder what had happened to make Carmilla be in hell.. a wonder that never stopped bothering you, and eventually you became a guardian angel! But there was a mix up one day, and you ended up getting tied to someone in hell.
And that someone was Carmilla, oh how happy you were to see her! Even if it was for a little bit till the mix up was fixed, but till then you tried to spend as much time with her as possible... For some reason, Carmilla just.. wasn't having it, rejecting any form of love you gave her
So, that's what began to break the love you had for her. You understood that it was highly possible for her to be a cruel woman because she was a overlord in hell, but you simply didn't care. Yet, Carmilla did. She always tried to get away from you but you followed
You knew very well that you would be leaving in a day or so, that's what heaven said how long it would take for everything to be back in order. As heaven simply suggested to stay put and out of sight, that's just something you pushed away since you cared a bit more for Carmilla
One day, You tried to calm her down since she seemed stressed about something. When you gave her a kiss on the cheek, she shoved you away, although the shove felt like it was hesitated
"We can't love each other.. and you know it. Your a guardian angel, I'm an overlord in hell." Carmilla said, she didn't want to get you into deep shit because you wanted to love her again. She didn't want to drag you down here! And that was something you both would need to accept
