Choi Beomgyu was not my friend. Even calling him an acquaintance would’ve been a stretch… No, Choi Beomgyu absolutely despised me. Which was a problem for two reasons: 1) his oldest brother was practically my soulmate, my other half, my best friend and 2) I'd had a massive crush on the little brat since we were kids.
I didn’t always know that I was in love with my best friend’s youngest brother. When we were young, I just liked to annoy him. And, that was easy. He was so easy to rile up, especially compared to Soobin—who was pretty chill and patient with everything—but Beomgyu would whine and that made it all the more fun to tease him.
When we got to high school, I had slowly stopped picking on Beomgyu. He started reacting with more hostility and became more withdrawn, which was the last thing I wanted. When the maknae stopped hanging around me—and by extension his brothers, I started to feel guilty and even missed him.
But why would I miss him so much? He was just Yeonjun’s kid brother.
I liked seeing him. I liked him following Yeonjun, Soobin, and me everywhere we went. I liked him begging to hang out with us. I liked him whining and pouting when I struck a nerve. I liked his attention. And I liked giving him attention.
But he was Yeonjun’s brother. I couldn’t like him. I shouldn’t. But I did.
See, slowly but surely, I started to realize that my feelings for Beomgyu were not the same as my feelings for Yeonjun or Soobin. And, once I realized that, it became hard to be around him when I knew he had grown to hate me while I had grown to love him.
And Yeonjun wasn’t stupid. He knew. Of course, he knew. Maybe not at first, but he figured it out…
“So when are you going to finally confess to my brother?” He asked once, junior year of uni, while we were in the library revising for a test.
Soobin’s head shot up from his own textbook, eyes wide, “Y/N-noona, listen, you know I love you but like, I don’t love you. Like, I like you. As a friend, but I don’t–”
“Not you, pabo.” Yeonjun rolled his eyes. I just silently dropped my head onto my notebook, beginning to bang my forehead on it repeatedly. Maybe if I did that enough times, I’d simply pass away. “Yah! Stop that.” Yeonjun lifted my face and flicked the sore spot on my forehead, making me wince.
“Wait…” Soobin’s eyebrows crinkled, lips pursed, “You like Gyu?”
“She doesn’t like him.” Yeonjun shrugged, “She’s in love with him.”
I stared passively at my best friend, his younger brother panicking next to us. “How did you figure it out?” I asked unbothered.
Yeonjun rolled his eyes again, going back to studying, “You aren’t as inconspicuous as you think you are. I’ve known for a couple years now.”
“Well, how come I never figured it out then!” Soobin shouted, earning a hush from the librarian.
“You aren’t her other half.” “He’s my soulmate.” We spoke at the same time.
And from there, the two only pestered me more. At least weekly, one of the older brothers would ask me when I was planning to confess, and I always answered noncommittally. So they took it upon themselves to start convincing Beomgyu to hang out with us again, much to his annoyance.
He would’ve been fine, happy even, to hang out with his brothers more… If I wasn’t around.
And on this day, the two were feeling particularly sadistic, having arranged for us to study and then subsequently bailing.
“Where are Jun and Bin hyungs?” Beomgyu eyed me suspiciously as I approached the table alone.
I shrugged, trying to quell the rising panic. I knew what those two were trying to accomplish. I never planned when to confess so they did it for me. The bastards. “Binnie texted me that Junnie and him had some errands to run first, and they’d bring us food as an apology in a little while.”
“Whatever.” He grumbled, eyes hardening at the very idea of having to be alone around me. He finally focused back on his work, a small pout forming as I sat across from him.
God I hated when he did that. It always made me want to kiss his stupid, pouty lips even more.
So this time, I did. If Yeonjun and Soobin were going to go to all this trouble to line up my shot for me, I sure as hell wasn’t going to miss it.
I leaned across the library table, cupping his cheeks, and kissed him. Those lips were as soft as I imagined they’d be, and for just one second, it was heaven.
Beomgyu ripped away from me, “What the fuck do you think you’re doing?” His voice held venom, and his eyes were wild. He looked absolutely appalled; I could feel my heart shatter.
But he couldn’t know that. As far as he knew, I was the sexy, sometimes a little bitchy, older best friend to his brother. So I settled back into my own seat with a smirk and shrugged. “Kissing you.” I grabbed my bag to stand. “But since that seems to be a problem, I’ll just go hang out with your brother.”
There was only a flicker of hesitation in his eyes; I could see it. He stood, grabbing me by the waist roughly as I passed him, and growled, “Fuck Yeonjun. You’re mine.”
“Wha–” Before I could finish a word, the breath was knocked out of me. Beomgyu’s grip on my waist was tight, his body pressed against mine, as he held me against the library stacks—out of view of the librarian, of course.
“Shut up.” His voice was deeper than I remembered it ever being, rougher. As was his touch. The contrast to the warmth from his breath on my neck and gentleness of his nose tracing up my jawline made me shudder. “You like me.”
“N– No, I don’t.” I was such a coward, but it technically wasn’t a lie.
Beomgyu pulled back, his grip faltering ever so slightly. But then, his eyes darted across my face, and he smirked deviously. “Don’t lie to me, Noona.”
I couldn’t hold eye contact anymore. “I don’t like you, Gyu…” My voice cracked and dropped to a whisper, but he leaned in closer. His eyes narrowed as he listened. “I’m in love with you…”
He sucked a harsh breath in and backed away. “You–” Beomgyu’s eyes were wild again, and he grabbed his bag with haste. He snatched my hand and stormed out of the library. “Come on.”
I didn’t know how it happened, especially so quickly, but before I knew it, Beomgyu had me back at his apartment and pinned to his bed in nothing but our underwear.
“Say it again.” He gritted out, his forehead pressed against mine while his body straddled my own. I was disoriented. He hadn’t spoken to me the whole rush here, and I was a bit over-giddy with the turn of events. My brain hadn’t really been keeping up with my heart since I kissed him initially.
“Say what again?” I finally managed to breathe.
“I love you, Gyu,” I whispered. He inched closer, his lips brushing over mine before he ducked down to nip at my ear.
My breath hitched, and he bit down harder on my earlobe. “I’m yours.”
The second his lips connected with the side of my neck, my brain short-circuited. Was this really happening? Did he want me back? Did he want me to be his? His. His. His.
He bit down, and I could barely contain the moan that I let out. He pulled away at the muffled sound, a dangerous gleam in his dark eyes.
“Uh uh. I wanna hear you. I want the neighbors to hear you. I want everybody in this building to know that you belong to me now.”
I didn’t know this Beomgyu, but god, I was more than happy to become acquainted. Just the smirk on his normally pouty lips had me gasping, and the trail of his nails scraping down my sides and digging into my thighs certainly helped.
Beomgyu’s mouth met my neck again, teeth grazing and nipping, bringing a low whine from me. He kept kissing down to my collarbone, sucking his mark there, while his hands danced closer to where I needed him. “What do you want?”
“You,” I whimpered, feeling his fingers graze the apex of my thighs.
“I know that, jagiya,” Beomgyu chuckled. He pulled away to peer down at me, amusement danced in his eyes. He looked at me with happiness, something I hadn’t seen in years—no, this had something more. He looked at me with love. “But where do you want me?”
I brought my arms around his neck, pulling him to lay down beside me, our legs instinctively tangling together. “I want you everywhere, Gyu. I want whatever you’ll give me. I just want you.”
His smile brightened, but his eyes darkened. Beomgyu leaned in to kiss me properly while his hands pushed my underwear down my legs. We laid in each other’s arms, making out while he removed my bra and his own underwear. It was no longer so feverish; the want and desire were still prevalent, but it had taken on a different kind of heat.
I pulled away just enough to meet his eyes. “Are you sure you want me?”
“I’ve never been more sure of anything in my life.”
Beomgyu leaned in to kiss me once more, but I stopped him, mumbling, “Then take me.”
I felt that devilish smirk form once again against my lips, and his grip tightened ever so slightly on my hips, slicking the head of himself over my slit as he lined himself up with my opening.
“Oh, jagiya,” he moaned, “We’ve barely done anything, and you’re dripping for me. Really want me to just take you, huh?”
“Yes, Gyu, please ju–” I was begging, but cut off as I felt him thrust all the way in one swift motion. The sentence died in my throat with a loud grunt, not of pain but pure pleasure.
My eyes rolled back, feeling Beomgyu dragging against my tight walls nonstop. We had never done this before—only in my imagination—and yet, he knew just the right way to move, just the right moments to speed up and slow down, just the right time to pull all the way out only to slam back inside, just the right way to roll and grind his pelvic bone against my clit to have me a whining, babbling mess.
I could feel myself edging closer, toeing the cliff that I desperately wanted to fling myself over. And somehow, Beomgyu was able to tell.
“Don’t you dare cum without me, jagiya,” he growled, pushing me further towards ecstasy. “I want to cum together.”
I was dizzy and sore and lightheaded in all the right ways. I could barely speak, barely think. I could only focus on how badly I wanted to hold it together, to be good for him, to cum with him.
Beomgyu let out his own, absolutely sinful, moan as he peered at how blissed out I was. His hair was obviously damp with sweat, sticking to his forehead, and yet, he’d never looked more beautiful. One hand clamped tightly on my hip, keeping the heavenly tempo as he ground deeply into me, the other cupping my neck, Beomgyu seared me with another kiss and growled into my mouth. “Cum.”
Falling over the cliff felt like flying. Falling over it with him felt like heaven.
When I managed to come back to my own body, Beomgyu had already returned from the bathroom with a washcloth, gently cleaning both of us up. He smiled softly, his eyes full of adoration, when he climbed back into bed with me. We rested like that for a while, just curled up around one another, before he broke the peace.
“So how long have you been in love with me?” Beomgyu beamed smugly.
I snuggled into his chest, embarrassment burning through me knowing that he was going to hold this over me forever. Call it karma for my years of tormenting him. “A long time… High school maybe, but I think I’ve liked you even longer.”
He giggled, something I hadn’t heard in years. “I’ve been in love with you a long time too, y’know. I remember having the biggest crush on you whenever you would come play with us when we were little. But you always teased me and gave Jun-hyung all this adoration, and then when we got a little older I remember telling a friend that I still kind of liked you. They told me I could never ask you out though; it was against ‘bro code’ since you were hyungs’ friend. I wasn’t going to listen, but it kind of got in my head. I thought maybe you liked Yeonjun-hyung or even Soobin-hyung since you were always so sweet with them. And then… I don’t know, even the teasing stopped, and I figured you were bored of me or just put up with me for my brothers.”
His voice saddened as he spoke, and I peaked up to see the far-off look. “Never, Gyu. It’s always been you… You were so cute when you whined and pouted, but then I felt like you started to hate me so I backed off. I’m sorry we wasted so much time.”
Beomgyu smiled gently, pressing a kiss to my forehead. “It’s okay, Noona. You’re mine now. That’s what matters.”
I settled on his chest again, closing my eyes to rest and enjoy the feeling of him tenderly caressing my back, but was interrupted by the sound of a door closing.
“So do you think she told him? Do you think it went well?” Soobin’s voice sounded from the common area.
Beomgyu jumped as the bedroom door slammed open, and I whipped around with the sheets held tightly to cover me. Yeonjun grinned evilly from the doorway, a very astonished Soobin behind him. “I think it went very well.”
