At first, Sukuna attended such a dubious educational institution, and even as a teacher, and even mathematics - to observe people. He knew, he was well aware, that his subject was not easy. The dubious pleasure fueled his bubbling ego gradually, slowly, but briefly and sensitively, so relying on his help during the control work or the usual pre-test was one of the most terrible things.

Naturally, you couldn't escape his strictness either. He considered everyone to be nobody and made no concessions to anyone, without saying a word and without starting such an extreme conversation about urgent grade correction, even with the smartest excellent student who suddenly received a two for independent work.

At first, you were one of the simplest, according to him, younger students, nothing special. However, just a little bit, perhaps to dispel boredom, Sukuna became interested in how you were trying to get his attention.

It all started with an exchange of glances; Sukuna noticed how furtively you were watching him, how a slight awkward blush appeared on your pale cheeks and how you constantly looked away when Sukuna's hellish red eyes turned to you with a mute question about your academic performance, and not about how and for what reason you did it. Over time, he also couldn't help but cast weak, cold, and stern glances in your direction. And it only seemed that your clumsy academic performance had improved. Fives even for the control work have become commonplace.

A physical touch followed; the way you timidly accepted your work, the way you tried not to blush at the touch, the way Sukuna's face even tried not to curl into a smirk- something in it ignited. Something dark, deep, such that he blamed himself for being able to experience such feelings at all.

The last step turned out to be that he invited you to his private classes away from everyone. In the middle of his damn apartment, where he never waited for anyone. He wasn't going to give anyone personal lessons at all. But even there he remained strict. So much so that with a slight movement of his hand, he scared the poor little girl and made her bite her lips when she heard a stern, steel-cold voice. But he'll be damned if he won't admit that he had a damn hard dick back then.

And he would be a real devil if he didn't agree to give the girl extra lessons after school today. But he was the devil. And allowed you to come to additional classes. Even considering how tired he was and how his head hurt. But even then, almost without paying the slightest attention to you, he was able to notice that you were completely not listening to him, as if you were immersed in your own world, focusing on one point. — "Are you going to waste my time so brazenly, brat?" — The voice was harsh. Making you shudder with sticky fear again.
