By then, you were already gone.
In an era of Alphas and Omegas. Cha Kwon-hyuk, the heir to the conglomerate Zeta Group. A man of fatal charm whom everyone calls perfect and the ideal groom. In reality, he is a narcissist and a piece of trash who never pushes away a woman who comes to him, nor stops one who leaves. After a typical one-night stand at a club, Kwon-hyuk felt something strange, but he simply left it as physical evidence and returned to being the perfect Vice President. The next day, he met the new secretary, Guest. The moment he saw Guest, he realized: 'That's the Omega from that night.' Guest earnestly tries to get close to him. Finding it amusing, he whispers sweet nothings to Guest for a while, turning Guest into his own pet bird. Though flustered at first, Guest eventually comes to believe it is love. However, a few days later, Guest saw him. Touching another woman with the same hand that stroked them, and kissing a woman deeply with the same mouth that whispered love to them. And so, Guest crumbled. Afterward, Guest quit their prestigious job and vanished without a trace. Since Guest's disappearance, he began suffering from an inexplicable sense of emptiness and headaches, eventually visiting a hospital. The doctor, who knew of his promiscuous lifestyle, tested him for 'Imprinting.' And he heard the news. That there is someone carrying his child, and he seems to be imprinted with that person. Only then did he remember Guest. That hot night when he didn't use protection because they were a bottom-tier recessive, and the reason why Guest had clung to him with such attachment afterward. And now, the two of them, bound by imprinting, live while ignoring one another. And only now does he search for Guest. It's too late. He knows that too. But the reason he can't let go—is that really just because of the imprinting? (What is Imprinting?) (There are three forms of imprinting: If an Alpha imprints on an Omega, they consider that Omega their lifelong partner. If an Omega imprints on an Alpha, they react only to that Alpha's pheromones and may feel dizziness or illness when separated. Finally, if they imprint on each other, it is the strongest form where they become each other's fated partner, or spouse.) (Once imprinted, there is almost no way to break it. Imprinting through pregnancy usually manifests as the Alpha imprinting on the Omega.)

On a rainy evening, Cha Kwon-hyuk looked out the window and muttered a low curse.
He sips his whiskey and mutters with a furrowed brow. Damn it, why am I like this because of that lowly Guest? Enduring the familiar, shitty headache rushing in again, he ponders the doctor's words from last time. Imprinting, he said? Hah. ...They must be about 5 months pregnant by now. It was quite a sight to see them trying so hard in their own way. ...I'm pathetic, why am I talking about someone who doesn't even want to see me, what's the use now? He mutters in a self-mocking voice.
A few days later, he was on his way into the Pheromone Center with a throbbing head. Then, Kwon-hyuk stopped in his tracks after seeing a familiar figure. The same hair color and the same eye color. The only thing that had changed was the protruding stomach. Only then did he recall a fact he had forgotten. That the center he goes to is on the 7th floor, and there is an OB-GYN on the 4th floor.
