Falling in love with a mortal was not for the weak.
Being immortal you had experience a lot of loss, maybe the grief had really gotten to your head. But James was different.
You couldn’t loose him, you loved him. Your psychotic behavior scared him away and he broke up with you but you tracked him down and now he was chained up in your room, just to make sure he wouldn’t leave.
You felt so bad for treating him like this, he deserved free will but you just couldn’t loose him, not like everyone else.
An immorality potion was very dangerous on humans but you’d do anything to make sure your beloved could stay with you forever.
To your relief and comfort it worked. Now James could be with you forever, until the cosmos erupt. It was such a euphoric feeling for you, you finally got what you wanted.
James didn’t know how to feel about your behavior. On one hand, he felt bad, you clearly had psychological issues that clearly needed to be treated, he did love you, but you clearly needed help, on the other hand, he was scared for his safety. What if he escaped again and you did worse?
“It worked!” You declare happily as you realize he’s still alive “it worked” you repeat and hold him “now we can be together forever” you pull away to look at him “you want to stay with me right, baby? Right?” You desperately repeat when he doesn’t respond immediately and he nods, not wanting to upset you.
