Muwan is an Omega, but one day he transmigrates into an ordinary world.
There are no Alphas or pheromones in this world, yet there are always men who like to cuddle up to him!
He thought he was destined to be alone for the rest of his life, until one day he smelled pheromones on his homophobic roommate!

Zhou Yixu is tall, long-legged, and aloof, the ideal straight guy, yet he is also cold and homophobic.
Despite being homophobic, Zhou Yixu treats Muwan inexplicably well. When it is cold, he puts Muwan's feet against his stomach to warm them. When it is hot, he sleeps beside him and fans him.
But Zhou Yixu is known for being homophobic. So even when the two get drunk and accidentally help each other out, Muwan firmly believes they have nothing more than ordinary brotherly affection.
Until one day, he smells pheromones on Zhou Yixu!
Thinking back on everything that happened before, Muwan suddenly gets it: Aren't Alphas and Omegas a perfect match? Got it. He's playing hard to get, right?
But from then on, the more they spend time together, the more things seem off to Muwan.
One day, unable to take it any longer, he pins Zhou Yixu against a wall in a corner of the classroom building.
"What's going on with you? You can't expect me, an Omega, to be the one to confess..."
And Zhou Yixu runs away...

Zhou Yixu is a top Alpha who transmigrated from an ABO world into an ordinary one.
He always thought he was an exception, since his instincts made him strongly averse to the scent of his own kind.
Then one day, his sweet, soft, ever-present roommate suddenly tells him, blushing, that he's an Omega.
Zhou Yixu: ? I must have gotten up too fast.

Rejected, Muwan is devastated and avoids everyone for a long time.
But one day, when someone is confessing to Muwan, Zhou Yixu, tall and long-legged, pulls him away in front of everyone. His usually calm eyes are now filled with anger and hurt.
"Wanwan, you were right. I was playing hard to get. Don't leave me..."
Muwan: ...
Get your mouth off mine first!!
Bonus scene:
After they get together, their relationship is always good, except when it comes to marking.
This makes Zhou Yixu sense that something is off.
Finally, one day, he can't help asking Muwan, "Are you really an Omega?"
Muwan blinks innocently. "Of course I'm an O, as in orange. Aren't you an A, as in apple?"
Zhou Yixu: ???
Fine, he can be one too. Then mark me again...
