In the end, he slept with Seo Kyo-Shin.
After his first time, Shin-Yeon lay in Kyo-Shin’s bed, unable to move a single inch.
He had genuinely thought he might die. That was the price of a recessive omega facing an extremely dominant alpha for his first experience.
'My whole body hurts so much I can’t even move a finger.'
Kyo-Shin, completely out of control, hadn’t stopped even when Shin-Yeon lost consciousness.
Shin-Yeon had blacked out several times in his arms, unable to handle the pleasure. And every time he woke up, they were still in the middle of it—enough to drive him insane.
Pinned down, his wrists held in one hand as he was forced face-down, he had no choice but to take everything Seo Kyo-Shin gave him.
'The baby’s too delicious—I forgot how to stop. What should I do? Baby, eat every last bit of me.'
'If you look this pretty and this lewd, you should’ve run before you caught an old man’s eye. Teasing me like you’re sexy, asking for kisses…'
'Haah… look at that face—baby’s gone crazy because I taste too good… smart little thing, even knows how to take an alpha cock.'
Filthy whispers, thick with heat, had murmured low against his ear the entire time.
In the end, Shin-Yeon spent a full twenty-four hours in Kyo-Shin’s arms, enduring a maddeningly long and brutal first experience.
The last thing he remembered was being carried into the bathroom in Kyo-Shin’s arms before passing out completely.
The next morning, he still couldn’t move from the bed.
It felt like his skin had been rubbed raw everywhere. But worse than that, it was as if the entire lower half of his body had disappeared.
His waist ached terribly, and especially… that private place deep inside felt like it had been burned out, strange and painful.
'If I want to protect my ass, there’s only one option left.'
'…Run.'
He’d spent the night with Seo Kyo-Shin. Now he really had to leave.
Click.
“Baby, you’re awake?”
Kyo-Shin opened the bedroom door and walked in. Dressed in refined loungewear, he approached and sat beside him.
For some reason, today Seo Kyo-Shin looked dazzling—like not one, but three suns were shining at once. As he stroked Shin-Yeon’s cheek, he said,
“That pretty face of yours is a mess.”
“…You’re seriously awful.”
He’d cried and moaned so much, but beyond that—trying to take something so big it wouldn’t even fit in his mouth had left his throat sore too.
His voice completely wrecked, Shin-Yeon muttered weakly and turned his head away.
“You’re shining so much you’re going to destroy the planet. I’m dying here, and you’re perfectly fine all by yourself… damn it. So mean.”
As Shin-Yeon squirmed and burrowed under the blanket in protest, looking exactly like a sulky baby kitten, Kyo-Shin couldn’t hold back his laughter.
“Haha, you’re right. Only I came out of it refreshed. My baby wore himself out trying to devour me.”
Kyo-Shin leaned down, wrapping his long arm around him and pulling him into his embrace. He tugged the blanket down and pressed kisses to his hair, the corners of his eyes, his cheeks.
“It’s been a while. I didn’t pace myself.”
If Kim Shin-Yeon had only been moderately delicious, he would’ve stopped partway through.
But he’d tasted better than any delicacy. He’d wanted to stay tangled with him for a full week—barely stopping only because he thought the boy might actually die.
Rubbing at the corners of his lips as if to hide the way they kept curling upward, Kyo-Shin leaned in and whispered against Shin-Yeon’s ear.
“Did you know? There’s probably a path inside you now shaped exactly like me.”
“…!”
Startled, Shin-Yeon immediately touched his stomach with both hands, and Kyo-Shin burst out laughing.
“Haha. I need to stop by the office for a bit. Stay here and rest, baby.”
“I have something to say…”
“I’ll listen when I get back. Right now, you need sleep. Your eyes are already drooping.”
Kyo-Shin gently stroked his hair, watched him drift back to sleep, then stood up.
After changing into a suit and putting on his coat, he considered returning Shin-Yeon’s phone—then decided against it and headed for the door instead.
“…Kim Shin-Hee is back.”
The situation had deviated far too much from their original agreement. That meant Suhan had violated the contract.
A twisted smile spread across Seo Kyo-Shin’s lips as he considered how to use that to his advantage.
***
After Kyo-Shin left for work, Shin-Yeon, who had fallen asleep again, dragged himself awake an hour later, looking utterly worn out.
He barely managed to get out of bed and practically crawled to the bathroom. Standing under hot water, he tried to loosen his aching muscles as much as possible.
Staggering back out, he found the clothes he had taken off earlier and put them back on.
The clothes he’d come in were ones Kyo-Shin had given him. He liked them a lot—but it didn’t feel right to take them with him.
“….”
In the dressing room, thick with Kyo-Shin’s scent, Shin-Yeon approached a neatly arranged suit and pulled it into his arms.
“I like you. I really like you.”
After breathing in Kyo-Shin’s scent deeply, Shin-Yeon went out into the living room, found a notepad and pen, and sat down on the floor.
Because pathetic, shabby Kim Shin-Yeon had panicked about becoming homeless, he’d ended up liking someone for the first time.
He even went on a date at his house with someone he liked…
“…That counts as a date, right?”
They’d held each other, kissed—and in the end, he’d even lost his virginity.
Even if it was a business engagement, he had crossed a very real line with his brother’s fiancé.
“Kim Shin-Yeon, you need to stop doing crazy things right here. Executive Director Seo is going to marry your brother….”
Holding the blank page and pen, his eyes reddened, tears pooling as he stared up at the ceiling to keep them from falling.
“…Sniff.”
After hesitating for a long time, he finally began writing an apology for bothering him all this time, along with a message of thanks.
“My clumsy flirting and my proposal were sincere. Of course… to you, Executive Director Seo, it might have seemed like nothing more than an annoying joke, but I meant it.”
“Yeah… that’s why you never once gave me a serious answer… hic—”
Tears streamed down his cheeks as he kept writing, not even bothering to wipe them away, continuing his farewell.
“I hope you’ll be happy, Executive Director Seo. Please marry my brother, the one you truly want, and be happy.
As for me, the one who got in the way, I’ll return to where I belong.
Please stay healthy, and forget everything that happened between us.”
After finishing the letter, Shin-Yeon curled up and cried for a long time before finally forcing himself to stand.
“…At least I got one memory out of it.”
Pulling the hood of his padded jacket low over his head, Shin-Yeon left Kyo-Shin’s house.
Lost in sadness, he didn’t even realize he’d left his phone behind until he arrived home by taxi. At least he still had his wallet, so he managed to pay and get out.
“…Haah.”
Only now did the guilt hit him—he had seduced and slept with his future brother-in-law.
Standing in front of the gate in the cold winter wind for a long time, Shin-Yeon finally pushed it open and headed inside.
The moment he opened the front door, warm air greeted him—along with the sound of his parents and his brother laughing together.
Whenever Shin-Hee was home, Shin-Yeon always felt like an outsider. Returning to that familiar dynamic weighed heavily on him.
“I’m back…”
“Shin-Yeon! Where have you been?!”
Shin-Hee rushed over, startled.
Their parents, on the other hand, had already heard from Kyo-Shin that Shin-Yeon had been with him, so they knew where he’d been—and were too busy exchanging uneasy glances.
They still hadn’t told Shin-Hee that, because he had run away, Shin-Yeon had stepped in and proposed to Seo Kyo-Shin to save the family.
Their excuse was that it would be too much of a shock for their eldest son, who had just returned from the hospital and was still recovering.
“Now that Shin-Yeon is here, let’s talk. Shin-Yeon, come sit down too.”
Seeing his brother’s confused reaction, Shin-Yeon realized.
“You didn’t tell him anything?”
“Wait—what? What are you talking about?”
The strength drained from Shin-Yeon’s shoulders.
He hadn’t really expected much. Still, if his parents had thought about him even a little, he’d hoped they would’ve explained things to his brother beforehand.
But no matter what Shin-Hee did, their parents had always doted on him instead of scolding him.
So of course, the problem that should’ve been a major confrontation had naturally been dumped onto Shin-Yeon instead.
'It’s always been like this. Nothing new.'
It still left a bitter taste in his chest, but he chose to accept it.
'I messed up pretty badly too, so I can’t exactly say I did nothing wrong.'
“You talk first.”
Turning away from his parents and brother, Shin-Yeon went into his room and pulled out a suitcase.
He packed the clothes and essentials he’d need right away, then took out the savings account he’d been building since childhood.
Thanks to the saving habits his mother had taught him, Shin-Yeon had consistently put money away.
In elementary school, he saved his holiday allowance.
In middle school, he deposited 100,000 won every month for three years.
In high school, since he spent most of his time with Seol Yi-Jun and Ji Won-Min and didn’t really spend money, his allowance piled up untouched. Saving 300,000 won a month for three years had left him with over fifteen million won.
“With this, I can survive on my own for a while.”
Since his family didn’t know about this money, Shin-Yeon quickly hid the bankbook in his suitcase. He also found an old spare phone he had used before and slipped it into his pocket.
Just as he closed the suitcase and wrapped a scarf around his neck, the bedroom door burst open.
Kim Shin-Hee stormed in, eyes blazing, and struck Shin-Yeon hard across the face.
Smack—!
“You crazy bastard—how dare you try to steal your brother’s man?! Do you have any idea what you’ve done?! You piece of trash! Who do you think you are, stealing someone else’s man?!”
Thud—!
Grabbing him by the collar, Shin-Hee shook him violently before swinging his fist into his face.
As Shin-Yeon, slightly smaller than him, took the blows without resistance, their parents rushed in belatedly to stop Shin-Hee.
“Kim Shin-Hee! What do you think you’re doing to your brother?!”
“And what exactly did you do right to be attacking him like this?!”
“Seo Kyo-Shin is mine! My fiancé! Fuck—people can lose their way sometimes! What, did you just sit there and enjoy watching him seduce my man?!”
Shin-Yeon had expected this kind of explosive reaction.
Wiping the blood from his nose and mouth, he stood up and spoke expressionlessly.
“The real piece of trash is you, Kim Shin-Hee. You drained your fiancé’s money and slept with every alpha you could get your hands on. You were the one screaming you didn’t even want Seo Kyo-Shin—now suddenly he’s your man?”
