A Beta Couple's Second Differentiation

Shen Yu and Gu Chao were two perfectly ordinary betas.

They depended on each other in a poor, underdeveloped little town on the edge of Zone Five, repeating the same humdrum life day after day. The only comfort they had was each other.

They'd lived that way for ten years, so naturally they got married.

Adult betas have a ten percent chance of a second differentiation. As luck would have it, before the ink on their marriage certificate was even dry, they both went through it.

Good news: One became an alpha and the other an omega.

Bad news: They switched roles.

Even worse news: Their pheromone compatibility was an astonishing one percent.

Their still-new marriage fell into crisis, and their ten-year relationship was put to the test.

In response,

Shen Yu decided he had to do something to salvage it.

He buried his face against the gland of the person society now called his former husband and current wife, took a huge sniff, and smiled through a pained expression: "Wifey, you smell nice. Gag. Wifey, you smell nice. Gag."

That night, Gu Chao spread his legs, a copy of The Guide to Healthy and Harmonious Alpha-Omega Relationships still in his hands. With a calm expression, as if discussing what to eat tomorrow, he said, "Now that we've become an alpha and an omega, why don't we follow the usual alpha-omega routine?"

Shen Yu was once an orphan. For a long time in the past, and even into the endless future, Gu Chao had been everything to him.

He never thought the relationship he'd worked so hard to build would ultimately fall apart.

Gu Chao abandoned him, returned to the glitzy Zone One, and got engaged to a top alpha. He didn't even say a word before he left.

Day one: Shen Yu was miserable. Maybe breaking up was the sensible choice.

Day two: Shen Yu couldn't make heads or tails of it. Why did he abandon me?

Day three: Shen Yu shoved their marriage certificate into his pocket and booked a ticket to Zone One. Damn it, he wasn't letting this marriage go without a fight. Gu Chao, you're dead! I'm suing you for bigamy!

Probably a silly romantic comedy

A very short story

Very silly and rather naive, so don't read it too seriously orz

Theme: Love means needing each other and being needed in return
