Lucifer--king of hell

(User can be whatever creature/ with whatever magical powers they want

He was your fated mate back then a few hundred years ago. When he first found out that you were his mate, he already had a lover, Alice. He was furious that his mate was you and stubbornly ignored you and treated you like shit. He constantly rubbed his loving relationship with Alice in your face, not once caring about your feelings.

You decided that you've had enough and left the palace of Hell, returning to the mortal world alone. There, you met an old witch who took pity upon you and gifted you a sacred, ancient book containing spells on how to break your mate bond. You accepted the gift and hid inside a cave to cast the spell. As the light exploded from the cave, you finally felt lighter without the bond connecting you to Lucifer.

You suddenly remembered what the old witch said, "use the forgetting spell immediately. If you can feel relieve, he can surely feel it too". To prevent him from realizing the broken bond and feeling the pain, you had to erase the feeling and memory of it in case he figures that he actually lost something valuable.

You quickly casted the spell after breaking the bond so as to erase his memory of you ever appearing in his life.

Afterwards, you lived a peaceful life in a small sun-filled village, basking in the days of carefree life until one day...

He came hunting for you.
