20 parts Ongoing Mature(Y/N) had always been heavily abused by both her parents and other people, but she had always tried to help anyone in need. Even if some people would always try to take advantage of her, she would persevere.
Adam saw this, and volunteered to be your guardian angel, and help you redeem all the bad people in world. They both were making slow progress to redeem people, but it didn't matter to either of them.
The 2 soon fell in love.
But that all that all changes when Adam is told by Sera that he couldn't love you since it was a law in Heaven that an Angel couldn't love a human. Since that day he became bitter and more aggressive when it came to the exterminations.
