Y/N - you are working on a night shift. You are just scanning the customer's items, processing payments and handing back the change when you saw a blonde, tall guy out of the corner of your eye. You greeted him warmly, "Hello sir, welcome to our store! Feel free to get anything you need. " I said with a soft smile on my lip.

"Hm..." His voice cold and deep, different from the other customers I've spoken to. Not long after, he approaches the counter with a carton of strawberry milk and a bag of chips. He sets the items down, and you scan them before checking the total.

"The total of the price is ****" I said warmly again with a small smile on my lip,

"She smiles a lot..." He thought, smirking slightly. "Out of all the cashiers I've met - who looks like they want to quit already, she's the one who's been smiling at me... strangely warm. Interesting. " He thought again.

After Y/N giving him the change, he then started walking away. Before he could fully step outside, you called out.

"Hey!" You shouted.

"Hm? Is something wrong?"

You picked up a slightly big strawberry-flavored lollipop and hands it to him. He stands still before he fixes his composure and takes it from your hand.

"Please come again if you have time! Oh! And this lollipop... we give to customers, for free, actually. " You said with a soft chuckle.

Suddenly, his heart started doing flips. A soft pink tinted his cheeks and ears, and his eyes were slightly wide. He then adjusts his glasses with his finger before fixing his composure again. "t- thanks, I guess." he stutters, He smiled warmly at her.

You smiled back and suddenly, someone walked in to the store. A dark grayish-green hair with the same jacket, dark gray with the same logo as the blonde-haired guy, it's his teammate. "Oh, Tsukki, what are you doing here? "

"Tch, just bought some strawberry milk." He blushed slightly in embarrassment.

The guy just chuckled it off before questioning suddenly. "Tsukki, I know this is sudden but... how was it? What happened? What did she say?"

The blonde guy snaps, and looks at him before darting away. "Got... got rejected." He says running a hand through his neck. The green-haired guy, eyes widen slightly with a look of concern in his eyes.

"Oh Tsukki... are you okay?"

"yeah."

"Are you sure? Well if you're really okay then... I'm glad. Oh wait here, I'll pick up some items here." The green-haired guy looks at me with a soft, gentle smile. You smiled back and greeted him warmly. As the guy wandered off, I look at the blonde guy with a look of concern too.

"I'm so sorry, it hurts doesn't it?" You gave him a reassuring smile. "That's okay, there's more of them you know? And also, Love takes time. " The blonde guy blushes, immediately looking away for a moment to calm himself. "Thanks, that was... sweet of you."

You chuckled, "It's no problem, actually. And see that lollipop you're holding? I only give people candies only, if they are kind back to me, even though my manager said to give them to every customer... and yeah, maybe it'll cheer you up a little, even though it's just candy. " You grin sheepishly.

"It... cheered me up a little, don't worry." he lets out a small smile to you.

The green-haired guy approached the counter and gently setting them down. While you were scanning the items, the two guys are talking peacefully together, "Guess their best friends." I thought. After processing the payment and gave him the change, they both waved goodbye at me and I waved back before they look forward to wherever their going to go.

I, will make you mine soon.

The night air feels colder than usual as you watched the two guys walk away, their silhouettes fading into the darkness. You held your chest, wondering why your heart was beating so fast just from looking at Tsukishima’s eyes—they were intense, like he was seeing right through you.

A few days passed, and he became a regular. Every night, like clockwork, he would appear at your counter. He doesn't buy much, just small things, but he would stand there, watching you. His gaze never wavered, never looked away. It made you feel... special, but also slightly... trapped.

One evening, a regular customer—a friendly guy who always joked around came to your line.

"Hey Y/N, you look tired today. Working too hard?" he smiled, leaning fully on the counter. "Maybe you should take a break sometime. I know a nice café we could go to."

You laughed politely, about to reply, when the atmosphere in the store suddenly dropped.

You felt a presence behind you. Cold. Heavy.

You turned around and saw Tsukishima standing there. He wasn't looking at you. His eyes were fixed on the customer, and his usual calm expression was gone. His jaw was tight, and his eyes were narrowed into a sharp, dangerous glare.

"She's busy," Tsukishima said. His voice was low, quiet, but it carried a threat that made the air very heavy. "And she doesn't have time for strangers."

The other customer looked at him and stops leaning on to the counter. "Whoa, man, I was just—"

"I said," Tsukishima interrupted, taking a step forward, towering over him, "she's busy. Leave."

There was something in his eyes that made you shiver. It wasn't just anger. It was pure, and full of possessiveness. Like he was marking his territory.

The other guy quickly mumbled an apology and left, looking scared.

Silence kicks in over the store. Tsukishima's gaze turned back to you. His expression softened instantly, but his eyes were still dark, burning with an intensity you had never seen before.

He walked closer, until there was barely any space between you. He leaned down, his face inches from yours, and whispered against your ear.

"Did I tell you you could talk to him like that?"

You swallowed hard, your voice stuck in your throat. "I... I was just being polite—"

"Polite?" He chuckled darkly, his hand reaching out to gently cup your cheek, his grip slightly tight, not letting you look away. "You smile at him. You laugh at his jokes. Do you have any idea what that does to me?"

His thumb brushed against your lip, his eyes darker than before.

"You belong to me, Y/N. Don't you understand that? I can't stand the thought of anyone else looking at you, touching you, even talking to you like that. It makes me want to lock you up so no one else can ever see you again."

He pulled back slightly, just enough to look into your eyes, his expression serious and terrifyingly sincere.

"So don't do that again. Because next time... I might not be able to control myself."

.

.

.

Y/N... My beloved,

.

.

.

.

.

I wanna lock you up so bad, kiss you, and mark you as MINE.

Days turned into weeks, and Tsukishima’s presence became as constant as the night itself. He was there every shift, watching, waiting. But now, things were different. He wasn't just watching anymore—he was taking over you.

He started showing up earlier, waiting outside the store until your shift ended. He never let you walk home alone anymore.

"I don't trust the streets at night," he would say, his voice smooth but leaving no room for arguments. "And I certainly don't trust anyone else near you."

One night, as you walked side to side, the silence between you was very heavy but comfortable in a... Slightly strange way. Suddenly, he speaks.

"You live at **Address**, right?"

Your steps faltered. You froze, looking up at him with wide eyes because of the shock. "H-how did you know that? I don't even remember when i told you..."

He didn't look at you, keeping his eyes forward, but a small, dark smirk played on his lips.

"I know everything about you, Y/N," he said calmly, as if it were the most obvious thing in the whole world. "I know what time you wake up. I know what you order for lunch. I know you bite your lip when you're concentrating and etcetera."

He turned his head slowly to you, his golden amber eyes locking onto yours, glowing with intensity in the dark.

"I make it my business to know. Because you are my responsibility. Everything you do, everywhere you go... it all belongs to me, seriously."

Your heart raced, a mix of fear and something else—something thrilling and dangerous. A few days later, you tried to talk to your coworker or a friend during your break, just like normal. But the moment you started laughing or sharing a story with them, you felt that familiar cold gaze burning into your back.

When you were alone later at the counter, cleaning the store before you end your shift, he suddenly pulled you into a quiet corner of the store, his grip on your wrist tight and firm but not painful.

"Why are you looking at them?" he asked, his voice low and dangerous. "Why are you smiling at them? Do you prefer their company over mine?"

"No, Tsukishima... kei, it's not like that—" you tried to explain, but he shook his head, cutting you off.

"Lies," he whispered, leaning closer until his forehead is toucching yours. "You belong to me, okay? Your attention. Your time. Your smiles. All of it... They should all be saved only for me. Just only me. If I see you giving pieces of yourself to anyone else... I might just have to take you away somewhere where no one can disturb us."

He brushed his thumb over your knuckles, his touch gentle but his words terrifying.

"Don't make me lock you up, Y/N. Because I will. And once I do, you'll never want to leave anyway." He smirks at you with an possessive and intensity in his eyes before letting you go and give you space.
