Well, This is part 2, I have one more part, and I think that is it.
Potions ended and nobody came up to Hermione or Draco. Things only started happening after Potions ended. The moment that both of them stepped out of the class, everyone horded them with question from all angles.
"How long have both of you been dating?"
"I though both of you hated each other."
"Wow Draco, you fell for the beaver?"
"Hermione, the Ferret?"
Obviously, the last 2 were from their friends. Hermione and Draco made it out of the crowds of people and attempted answer most of the questions.
"Since half way through the year."
"We did for a while."
"Yes Blaise"
"What is your problem with it, Ron?"
They eventually made it to the Great Hall for dinner. By then everyone except their friends had left them, probably to spread the news.
"Ok everyone left, now spill."
Harry and Ron were shocked but Harry decided to learn the whole story before judging. Ron, however, had other plans.
" Mione, What spell or potion does he have you under?"
Hermione started to look frustrated, and both her and Draco decided to tell the story to their respective friends.
It started with the beginning of the year. The war was over, and everyone came back for a repeat of seventh year. Draco and Hermione were head students. Before that year, both of them used to study together sometimes, but they weren't really friends. Being on different sides of the war easily caused rifts between them. Hermione believed that he wasn't a bad person, but obviously now wasn't the time to start trying to figure that out. 6th year ended, and they both didn't come in contact again besides in the manor. Hermione was grateful that he pretended not to recognize them, and that only added to her list of reasons why he wasn't that bad.
Their first night back, Draco and Hermione talked everything out. He spilled that he only became a death eater because his parent forced him to. He didn't purposefully hurt anyone beyond that night with Dumbledore, and he had only done it because Voldemort was going to kill his mother otherwise. He apologized to Hermione for everything he had ever called her, and she accepted it. They both decided to start a fresh friendship. They decided it was the best option anyway, because they now shared dorms as Heads. They didn't want to create a big uproar, so they decided to stay friends inside their dorms, or when they were alone, but when they were with others, they pretended to only tolerate each other. They no longer insulted each other anywhere, but they didn't seek out each other presence, or act overly nice. When their friends brought it up, they said that they didn't want to create disturbance as Heads, and that the other person really wasn't that bad. It wasn't a lie.
As the year went on, they both got closer and closer as friends. In public, they started showing more of their friendship. Nobody cared, and they simply referred to the Head issue over and over again. In secret, they started being attracted to each other. Neither could deny that they liked the other person, and romance brewed between both of them. Eventually, they both became a couple, but they chose not to tell anyone to avoid chaos and so that they could keep their own rooms, now that they had other reasons for it. Obviously the teachers would separate them, if they knew what the two of them did at night. Everything went on great, until that day in the potions room.
