Chapter 00: Prolog ✨

Atsumu felt uncomfortable in his own skin. He was nearing his heat and everything felt wrong, every texture against his skin set it ablaze or itching. He felt like he was wearing a too-tight sweater that was choking him, which was impossible since he refused to wear anything but a loose t-shirt these past few days. It still wasn't enough.

A whine clawed its way from his throat. He hated this. If those stupid Alphas had managed to pup him the last time, he wouldn't have to go through this right now.

A pout formed on his face and he crawled back under the blanket. Said stupid Alphas and his lovely Beta mate were all currently at work, leaving him alone in their house.

His eyes shut close and he tried desperately to fall back asleep, chasing the thoughts of all the fun he was missing out on at practice away which only led to him thinking of his mates. Although his heartbeat quickened and he felt the echo of love from his bond it also cause his chest to hurt with the heartache of being alone.

He clung to the blankets and sheets covered in their scents. Closest to him lay Kita's pillow emitting the lingering aroma of vetiver and ginger. It was mild and sweet compared to the other two, not as strong since he was a Beta yet to Atsumu it smelled like heaven and he buried his nose deep into the fabric.

It was reassuring but lacking the warmth and comfort having his mate actually by his side usually brought. He sighed and pulled the blanket above his head. Maybe if he blocked out the sun he could just sleep through this.

An Omega would fall into heat every three months and pre-heat was the worst part of it in his humble opinion. That was ever since he had mates to spend his actual heat with. It made things much easier and shortened the time he had to take off from work. Which meant he would be back to playing volleyball very soon.

...

Not for too long though if their plan would work. If it would actually take this time.

Ever since last month and following long discussions and carefully mapped out plans they were trying for a baby. It hadn't been an easy decision. Atsumu would have to pause his career and the overall stigma surrounding the return of an Omega in the sports world after such an event weight heavy.

It only fueled his spite to prove them wrong though and after talking to his coach, partially to alleviate Sakusa's concerns rather than his own, he was certain. He knew that the team had his back and as long as he didn't slack off while still being responsible he could do this.

Additionally, he had three wonderful mates at his side that would support him no matter what... except for right now.

He whined again silently cursing all three of them for having jobs to tend to and stupid society for demanding money for living and keeping them from him. And overall human nature and everything he could think of up to the sun itself, for shining brightly and allowing for harvest so that Kita had no choice but to leave.

The hormones of pre-heat always left him an emotional mess to the point where he didn't want to know what pregnancy would end up doing to him. But everything for the baby.

Deep breaths.

After much trouble, he managed to fall asleep... but not for long. He was rudely awakened by a sudden wave of warmth surging through his body, causing a groan to slip past his lips.

He didn't even need to think twice to know, his heat had started. And none of his mates were with him... great. His body felt as though someone had set it ablaze and he was torn between feeling uncomfortable and needy as the slightest bit of fraction caused pleasure to ripple through his system.
