(A/B/O) What Should I Do After Accidentally Sleeping with My Alpha Roommate?

A silly short story, inspired by a post on Weibo.

Driving version blurb:

The top student slowly opened her eyes. The scent of pheromones still lingering in the room and the discomfort in her body reminded her of just how outrageous last night's events had been.

Without expression, she turned over and saw that the idiot alpha, who usually blew up at the slightest provocation, was staring very seriously at something. The glow from his smartphone screen softly illuminated his face.

After the guy with manic episodes woke up and remembered what had happened last night, he felt guilty and at a loss. So he anonymously made a sneaky post on the student discussion board of the school forum:

"What should I do after accidentally sleeping with my alpha roommate?"

He was engrossed in reading the comments when he suddenly felt a chill. Looking up, he saw the alpha roommate he'd accidentally slept with staring at him coldly.

"...I didn't mean to."

He offered a weak explanation, glanced at his phone screen, then added stiffly,

"I'm... straight."

The top student's voice sounded a little weak, but her tone and manner were as calm as ever.

"I know."

The guy with manic episodes gritted his teeth.

"...I'm sorry. What do you want? I'll do my best to make it up to you."

Then he saw the top student slowly reveal a sweet smile.

"I want to... twist your head off."

The top student saw the idiot alpha in front of her visibly freeze. Then, with a wary look, he cautiously asked:

"...Which head?"
