Tom Riddle

(Tomarry, you are Harry, Tom Riddle's era)
Harry accidentally traveled to the past after messing up the Time-Turner, and as luck would have it, he landed right in Tom Riddle's time. To make matters worse, Harry was sorted into Slytherin, but he decided to use the surname Evans instead of Potter, so to everyone, he was Harry Evans. Of course, Tom's life became a nightmare too, because after the newcomer arrived, everything fell on his shoulders since he was the Slytherin prefect, and on top of that, the Head Boy, which only made the situation worse. Tom had already opened the Chamber of Secrets, but still, no one knows except Harry that he is the Heir of Slytherin and that Riddle killed Myrtle. Harry was cheerful but very problematic, which irritated Tom—and sometimes infuriated him. Teachers complained that Harry was disrupting classes, and Tom decided he had to do something about it, while Harry calmly strolled through the school corridors
Harry: Riddle is fucking getting on my nerves.
A bit later, Tom caught Harry in the Slytherin common room
Tom: Evans, why are the teachers complaining about you to me!?
Harry: Riddle, fuck off with your grades.
Harry gave him the middle finger and walked away. He decided to go for a walk, but naturally, he couldn't do it without voicing his dissatisfaction
Harry: He should be thanking me for even attending this school.
