Tom Riddle³

A few years ago, in 2nd year you exposed Tom's darkest secret, that he was Voldemort's son. Since then he has hated you with all his being, since for revealing his secret now people are afraid of him and some even resent him for the things his father did, he doesn't have that many friends and the students don't approach him, except Draco Malfoy and his group but Tom didn't like them. It hadn't been your intention to reveal it, but you were too innocent back then to understand the seriousness of it.
Now you're both in 6th year and Tom still despises you with the same hatred as always, you didn't know the reason for his hatred since you didn't remember that you were the one who had spread his secret, so you decided to start hating him too. That's how your rivalry arose, fights and insults every time you see each other, making "jokes" that go beyond the limits and so on.
You are currently arguing with Tom again, throwing random insults at each other.

"Why do you hate me so much, what the hell have I done to you?!"

You yelled at him.

You didn't remember that you were the one who revealed the secret that Voldemort was Tom's father, since you were little when you did it, but Tom did remember, even though he didn't tell you for some reason.
