Summary
In a world where your second gender determines your life, Atsumu is lucky that his twin brother and Alpha guardian Osamu supports him chasing his dream of becoming a pro Volleyball player although he presented as an Omega. After Atsumu meets the sharp tongued, but understanding Alpha Sakusa at the All-Japan Youth Training Camp, the young Omega is quick to fall in love. But when Atsumu’s heat doesn't come as planned another problem arises. Suddenly, it seems like Osamu might not be as open to the idea of Atsumu going Pro right after school, as the Omega initially thought.

"You're staring," Atsumu said, not looking up.
"Can you blame me?"
Atsumu turned, a spoon in his hand, a teasing glint in his eyes. "What, the chef's hat do it for you?"
"You know what does it for me." Kiyoomi's eyes dropped pointedly to Atsumu's ass. "Those shorts are a crime."

Kaito is three years old and absolutely certain there is a frog living in the clover patch.
There is no frog.
There is, however, an emperor who cleared his entire morning schedule to come find his family in the garden, a six year old who knows everything about painted lady butterflies, and an (his) empress who is eight months along and so full of love he doesn't quite know what to do with all of it.
The earthworm counts too.

Summary
The first thing Atsumu thought, upon being told he was to marry the Emperor of the Eastern Realm, was: "at least he's pretty."
This was not, perhaps, the most auspicious beginning to a great love story. But Atsumu had always been honest with himself, even when honesty was inconvenient, and the portrait the imperial envoy had brought, was undeniably of a pretty man. Sharp jaw. Dark eyes.
Atsumu had looked at that portrait for a long time.
Okay, he'd thought.'Okay. It could be worse.'

People who know him really well would say something along the lines of ‘hopeless romantic’.

Summary
Tokyo is drowning in crimes—more ruthless, more relentless than anywhere else in Japan. The Crimson Crows an alpha-based territory, a feared yet principled gang, have taken it upon themselves to patrol the city and fight back against the chaos. But their mission has come at a devastating cost. After a brutal clash with a rival organization, they’ve lost half of their members and now stand dangerously outnumbered, their strength fading against an enemy that only continues to grow.
Still, they refuse to fall.
Driven by the lives already lost and the future they’re desperate to protect, the Crimson Crows cling to a single, unexpected lead—one that could turn the tide in their favor. Strangely, it points not to the underworld, but to one of Japan’s most famous omega-based idol groups.
It sounds almost absurd. In a city ruled by violence, how could pop idols possibly hold the key to victory?
But in Tokyo, nothing is ever that simple.

Summary
34 year old Sakusa Kiyoomi is a Fire nation General in the year 1204. He has seen his far share of wars and won many of them. Nothing fazes him anymore. Nothing but the fire lord deciding Omegas are of equall standing to Alphas and can go to war. That bugs him. Sakusa is a traditional Alpha and this is just ridiculous. Espesially a certain brunette Omega who somehow managed to have a rank.

Summary
Every word was uttered in slow, measured cadences. Hung heavily in the living room. Like they weighed a tonne each, and Atsumu didn't understand why.
Didn't understand the gravity of the situation.
"You're now an Omega, Atsumu," his father said. Carefully. Tactfully.
A dive in his gut. Sudden. Deep.
"Considering you two are twins, your brother could present as an Omega too."
