A thawed heart
Our tale begins just outside Nagini's parents' house, her boyfriend Salazar has come seeking forgiveness.
Salazar shouted, "My one true love, I have come seeking Nagini!"
Nagini emerged from the house and asked, "What in Merlin's beard are you doing here, Sal?"
Salazar told her, "I thought deeply about what you said to me. How you wanted to feel pain again so we could be together even after death. Your words thawed my frozen heart and I have come seeking your forgiveness."
Nagini smirked. "For a man with a frozen heart until now, you have been doing a pretty good job."
Salazar laughed. "True."
Nagini smiled. "Of course I forgive you because whether we spend another 100 years or even another ten together, I will always love you."
Salazar replied, "I will always love you too."
