Tom Riddle is the defense of the dark arts professor, he's also the new Dark Lord but keeps is a secret. He's got a younger brothwr in the 6th year, Mattheo Riddle.

Tom has his eye on someone, Y/N Grindweld.. Gilbert Grindweld's daughter. Y/N is in her final year, 8th year and she's 18. Y/N is a Slytherin, trouble maker but oddly has all A's.

Tom refuses to do anything about his small crush, since Y/N is a student and he's the professor.
