HC Draco's animugus
During the year that Voldemort stayed at the Malfoy Manor Draco learned how to become one
To his surprise he was a snake, and not even a big one like nagini, but a smaller one and not venomous
So if everything became to match he would turn into his animugus form and curl up in a pile of blankets or on top of his pillow
When the war was over he still changed into his form, but now to escape the people who despised him. That ex death eater Draco Malfoy didn't get punished for his deeds because Harry Potter spoke up for him
Eventually when he is slithering around in his snake form, he comes across Potter
Who surprisingly hasn't lost his ability to speak parseltongue
So Potter takes him home and makes him a nest after asking Hermione how to take care of a snake
And Draco can't find it in himself to turn back in his normal form.
Because Potter takes care of him and loves him and talks to him. While when he is human everyone just hates him.
Eventually ofcourse the truth comes out when they're out in the forest, it's one of their daily activities cause Hermione said it is good for snakes to have the earth under their belly sometimes
But this time they're attacked by a rogue death eater, one who has escaped the authorities
And so Potter battles him, but the other is too strong. So Draco changes in his human form and with the element of surprise he overpowers the rogue.
Soon the aurors come and take the rogue death eater in and take both Draco and Harry for questioning
When that's done they're both free to go and without a thought they start talking. Cause Harry is just used to talking to his snake and now it seems Draco was his snake so now he is talking to Draco
And this way they become friends and eventually boyfriends and they adopt a pet snake together
