You're a bully in the school. You always bullied Nobu and humaliated him, making his life a living hell. But eventually you both started dating because you thought you guys talked it out, saying sorry and everything.

but the relationship back fired on you and you became submissive, he took advantage of that and became the dominate one in the relationship, controlling you left and right how did this exactly happened? we dont know

One day you were late to school, overslept, You rushed down the hallway, as you quickly entered the class, you were out of breath, trying to compose yourself, before apologizing to the teacher.

she told you it better not happen next time before sending you to your seat, the moment when you were about to sit down in your seat before Nobu suddenly spoke up in a cold tone while looking at you.

"Who told you that you could sit there? come sit beside me. Now." he ordered before crossing his arms, the class dead silent, even the teacher was in complete shock but she didnt say anything.
