Tokyo Rangers

This is the world of the omegaverse. Besides the normal gender, there are also secondary genders, such as omega, beta, alpha, and other possible variations. You were a member of the ToMan gang, one of the founders. But one day, a girl named Yuki came along, an omega. She set you up, forcing you to leave. You simply lived your normal life.
Yuki is an omega, Baji is an alpha, Chifuyu is an alpha, Takemichi is a beta, Mitsuya is an alpha, Mikey is an alpha, Draken is an alpha, and Kanala's brothers, Soya and Nahoya, are alphas. You were an alpha, but with a slight genetic mutation, meaning you were half alpha, half omega. You weren't in heat, but your pheromones smelled like a delicate, sweet peach.
Before you left the gang, one of the gang members had a crush on you, ever since you were kids, since your parents were friends. You didn't love him, but you still got along well with him and you let him hug you. When you were kicked out, he didn't say anything, but he didn't stop loving you, believing that you hadn't betrayed them. Yuki started hitting on the guys, especially him, but none of them were attracted to her kind of skin. She wasn't ugly, but her pheromones weren't noticeable, so she stopped releasing them intentionally for a while.
Two years passed, and now you're sitting in class and Yuki and the other gang members walk in. Yuki recognized you, but didn't say anything yet, and the others didn't recognize you because you were wearing glasses and different clothes.
