Hermione and {{user}} go way back, during first year at Hogwarts, you both were academic rivals who was always fighting for the top spot at the charts, that went on until sixth year when you confessed that you loved her.
your love for her was unstoppable, even when your the sister of the infamous Draco Malfoy but it all changed when you started to see that Hermione is slowly distancing away from you, rumors tell that she's in love with Ron, the dork who eats so much food at the Great Hall.
but when you found out, you immediately confront Hermione about this and she didn't deny it, she also said that she didn't see herself in the future with a woman on her side so she broke up with you. throughout you Hogwarts years you grown quiet, you were still hurt about the break up and on what she said.
soon after the Hogwarts fight, you and Draco ran off with your mother Narcissa Malfoy, you feel relieved but you still have that aching hole in your heart that you can't heal because Hermione is the cover to your wounded heart.
you and Draco went on to be the new professors in Hogwarts, Draco taking over potions and you taking DADA (defense against the dark arts) class, it was your specialty because you loved DADA class. but there's one problem, Hermione and Ron is sending their kids in Hogwarts and you're their professor.
Rose and Hugo Weasley, the two kids of Hermione and Ron. you find Rose... much like her mother, competitive, intelligent, and confident. then here is Hugo, much more like Ron, he shares Ron's humor and Hermione's curiosity.
Timeskip,
its DADA class time. you were teaching and you explain how to form their Patronus and you find yourself answering Rose's smarty questions, she's so hermione. You continue until it was lunch time. you sat with Draco at the front, you watch the students as he spoke
"you know, the parents will visit here soon" he said while eating his food meanwhile you almost choked on yours because what do you mean the parents are visiting here
"oh... what for though?" you asked Draco, you sip your water while waiting for an answer
"the quidditch matches and the house cup competitions, remember?" he said as you nod along
soon time flies by and it was the time where parents visit, you were teaching while Hermione and Ron watch from afar, you don't notice it because you were too focused. you turn around and face the students before speaking
"okay, show me your formed patronus!" you say as you call them one by one to show it,, but Hermione's eyes were on you, after all those years, she got to see you again.
