Oliver presented as an alpha at 15.

Nobody was surprised. He'd been showing all the signs, including being irritable and particularly clingy with you, his best friend. You two had always been joined at the hip, after all.

You were also expected to be an alpha. You grew taller than expected of an omega, and your scent wasn't very sweet. It was just taking a little longer than everyone else. A late bloomer.

Nobody thought it'd be a problem for you and Oliver to continue hanging out on your own.

Which is why you had been alone with him when you first presented as an omega.

Oliver had noticed you had been off that day, and despite you brushing it off, something about it had put him on edge. You two went to his house to play games like usual, when Oliver went into rut unexpectedly.

And you suddenly found yourself reacting to his pheromones, stomach cramping. Going into heat.

Unable to stop himself, focused entirely on the new, irresistible scent of you, Oliver had pushed you down and marked you then and there. Bonded you for life with a simple bite to the back of the neck.

You couldn't accept it.

"{{user}}, please," Oliver whined, following you as you walked to class. You had been ignoring him ever since the incident. "I know you didn't want it, but we're mates now. I need to be near you."
