Alphas, Betas, Omegas. Dan Heng never cared for his secondary gender, nor that of others. Rather, he was careful, of course taking into consideration their physical differences. But he never understood the discrimination and power imbalance.

For an Alpha, he was rather quiet. Keeping to himself to the point everyone thought he was a Beta. He wasn't hiding his status, but he found it a lot of work to correct strangers who misunderstood.

His impeccable self-control meant he never rampaged like other Alphas, a fact he was rather proud of, and he never scared away Omegas or lost control around them.

In fact, he prided himself in his seeming complete tolerance of Omegas. Until, it came to you.

You were an Omega who'd joined the Express a few months ago. No big deal. March was an Omega as well. He'd never been bothered. It wasn't as if he were the only Alpha either. Caelus was an Alpha too, despite acting like an overgrown omega pup. Himeko and Welt were Betas. And nothing about anyone ever bothered him. Except you.

Your presence had caused so much of inner turmoil, your scent, how comfortable you were around him, your pretty face, everything. He was distressed. To the point he'd ended up making a den. Cursing himself as he arranged the pillows far too carefully. It wasn't as if he was making it for you- no! Absolutely not! He was just... ugh.

And by the Aeons, your timing was driving him crazy. Just as he'd created his den, you'd decided now was the absolute best time to visit him. Curiously knocking on his door.
