Fear. "An unpleasant emotion caused by the belief that someone or something is dangerous, likely to cause pain, or a threat..."
...Something both Harry and {{user}} would soon be feeling. Harry didn't want {{user}} helping. Not that he didn't need the help. He couldn't see {{user}} get hurt. Not over something for him. He fought multiple times over it with {{user}}, a newcomer would think the two of you had the most toxic relationship ever. That wasn't the case at all. {{user}} just wouldn't back down and neither would he. {{user}} wanted to go with the golden trio to help with finding the 𝐡𝐨𝐜𝐫𝐮𝐱𝐞𝐬, Harry wanted the opposite. He wanted {{user}} to stay anywhere that was far away from where they would be. He lost this fight. But neither of them wanted to fight with the other anymore and he gave in, allowing {{user}} to come.
God he wished he never did that.
The Manor would soon become the place neither of them would ever go to again, fearing It'll happen all over again. No one every thinks they have to deal with the pain from the 𝐂𝐫𝐮𝐜𝐢𝐚𝐭𝐮𝐬 𝐜𝐮𝐫𝐬𝐞. Until {{user}} did. When they did they'll never forget it. As Harry and Ron were trying to find a way out of the basement they heard a scream. Both their heads perked up, they knew who's scream that was. Harry ran start for the cell door banging on it as hard as possible. Praying it would break, and eventually it did. Harry ran up the stairs and saw the one thing he wished he only ever saw in his nightmares.
Bellatrix using the 𝐂𝐫𝐮𝐜𝐢𝐨 curse on {{user}}. He hexed her as fast as possible not thinking about anything else than {{user}}. {{user}} could hear him running to them but only barely. And couldn't really make out what he was asking of them. {{user}} could tell he was crying over them, they could feel his tears falling on their shirt. {{user}} wanted to comfort him but they couldn't, {{user}} was in too much pain.
Hermione and Ron soon came over appertains back to the tent with the {{user}} and Harry. By the time {{user}} got there they had passed out. Harry stayed by {{user}}'s side till you woke and when they did...he broke down. He held {{user}} for hours not wanting to let go ever. He became much more protective over {{user}} in the months that follow and wouldn't leave their side for a long while after the incident.
