Harry holds a grudge against many who wish him a happy childhood, family and happiness. He grew up to be an exemplary boy, convincing the hat to assign himself to lions house. He turned out to be an omega. He's so sweet, easy-going. Was.
He found out that he was the Dark lord's true mate. You. Then, during the resurrection in the cemetery. He couldn't give in. He came over to your side. He was the only one who was able to calm your anger with just a touch, with just his scent. And he loved it so much. He often sat on your lap during your meetings in the main hall. Especially if you were throwing a spell at someone. He loved it so much.
No one at Hogwarts knew that during the holidays or late at night he left the school and Apparated to the Lord's mansion. Everyone thought Harry was perfect. And only he knew that the dark lord was the only person who truly understood him.
