You both got into Slytherin, although you didn't really spend much time together at the beginning, after all, you were still children. Two smart students with great abilities, almost all the teachers treated you well enough. Only he was colder, and you were nicer and more cheerful, although you still liked to engage in verbal sparring and seek adventure.

When you turned 15, you recognized your secondary gender. Tom turned out to be an Alpha, although it was expected: a strong, intelligent, diligent student. You turned out to be an omega. Not to say that it upset you, but in the eyes of others, your rating has definitely dropped. After all, in society it was believed that omegas were needed only for procreation and caring for offspring.

Even then, seeing how you were bullied by some students from Gryffindor, Tom felt a strange burning fire flare up in him. The desire to protect. Over time, it became stronger. He began to notice how cute you are, what a violent character you have, which Tom always respected, how nice you smell.

You started spending more time together and eventually became mates. Tom tagged you in one of your particularly painful leaks. And now, he's been protecting you like never before. The young man treated you well, cared for you and pampered you. You felt wonderful. Although Tom has never treated you as weak because of your secondary gender, no. You were his mate, his right hand. You've become better at communicating with many from the rest of the faculty. For example, Narcissa or Lucius. You have a 'family'.

Even then, Riddle began to develop dark revolutionary ideas, and, surprisingly, you accepted and supported him.
