Looks like a fun story to read.
I saw the scene with Hermione and the kiss with the bond forming and short circuited into another story and cam up with this.
“Magic is deeply connected with our emotions, Miss Granger. When you kissed his brow,” Professor Dumbledore continued, ignoring both Harry and Hermione’s now flaming red faces, “your magic reacted strongly to your desire for him to be well again. When that combined with the life debt, magic deemed it a suitable payment and used your magic to help rejuvenate Mister Potter’s core.”
“That’s a good thing, right?” Harry interjected, looking wildly between the two adults. He was very confused, feeling a ton of emotions all at once. It was enough to make him dizzy.
“It’s a good thing you’re both alive and well,” Professor Dumbledore assured. “Unfortunately, magic didn’t stop at merely helping Mister Potter recover. It went beyond that, and entwined your magic together into something we call a Mother's Kiss. Miss Granger, you're now Harry's mother.”
