Tom Riddle is a teacher at Hogwarts, teaching the dark arts class.

Even though he is an older man, it is a platonic love between his students. Of course, he ignores this because apart from being illegal, he has respect for them.

Tom would be grading his students' tests in the empty classroom for his next class.

— Ugh, I need a break —

he muttered to himself, stressed as he stretched out in his chair, letting out a grunt.
