Synopsis: Tonight's mission is in your hands, and you're eager to prove that you're capable of handling it on your own. Unfortunately, your plans are interrupted a bit sooner than you expected.
***
"I've got eyes on him," you mumble, pretending to fix your diamond earring as you adjust your earpiece. Surveying from the platform of the mansion's grand staircase, your eyes follow a man in a black suit as he turns the corner and disappears down a far hallway.
Chan's sigh rings in your earpiece. "Be careful."
"I can handle myself. Trust me."
"I trust you, Y/N. You know that. It's everyone else that I don't trust. It's your first time unaccompanied," Chan says.
"Like I said, I can handle it. Besides, the boys are always out by themselves and they're just fine." If you could see Chan right now, you know he'd be pinching the bridge of his nose out of stress, holding back from giving you a lecture on why your situation is different from theirs. You know his concern is out of love, and he would blame himself if anything were ever to happen to you. But this is your chance to prove yourself. Tonight, you'll be participating in an auction to get your hands on the Cromer, a powerful artifact that can control time. It's been rumored that ATEEZ has their sights set on it as well, so Chan had you do as much research on them as possible. Unfortunately for you, they're quite good at covering their tracks and keeping their identities under wraps. You know only a few of their names and faces, so you'll need to be extra careful about your approach to this.
The auction will begin in about an hour, and you'd rather not hear a lecture from Chan. "I'm going in," you whisper. Your black dress flatters your figure perfectly, and you're excited to show it off tonight. With a deep breath, you make your way down the staircase, your heels silent on the expensive red carpet.
Clusters of people stand together around the large space, sipping champagne and chatting amongst themselves. Many wives have separated into groups away from their husbands, who go on and on about their latest business ventures and investments. Understandable—how boring. You greet some people as you go, your charming smile in effect as their eyes land on you. One woman compliments your dress as you pass by, and you enthusiastically return her compliment, telling her that her own dress brings out her eyes. She blushes and tells you it's custom made, which basically means "my dress is worth twice as much as the average person's monthly paycheck."
You continue to weave through the crowds and admittedly get a bit distracted, still thinking about the woman's compliment. As you turn into the hallway you witnessed your target disappear into, you bump straight into an oncoming person. A strong arm wraps around your waist before you can lose balance on your high heels.
"Woah there, doll. Straying too far, are we?" A tall man with dark hair looks down at you, his eyebrows raised.
Park Seonghwa. Just the man you were looking for.
"My apologies sir," you say quietly, feigning innocence and avoiding his eyes. His arm leaves your waist after steadying you. "I was wandering in hopes of finding a vacant room to lie down...I'm afraid I've had a bit too many drinks too early in the night." You stumble for dramatic effect, hoping he'll eat up your lies. "I have to sober up before the auction," you say, shaking your head. "Daddy will throw a fit if I spend all his money tonight."
The man looks amused. "Yeah? Better be careful, princess."
"I can handle myself," you say for the second time tonight, stepping closer to trace the pads of your manicured fingers over the fabric on his chest. He tilts your chin up gently, and you meet his intense gaze. He's breathtaking. Suddenly, you have an idea that seems much more fun than your previous plans.
Sorry Chan, you think as you press yourself against Seonghwa.
***
You didn't find anything of importance on Seonghwa's person, but you did manage to slip a tracking device into his suit pocket. Chan should be able to access his location any minute now.
You enter the auction room fifteen minutes before the event is scheduled to start, scanning the tables for your seat. It's dimly lit, a majority of the lighting coming from a screen behind the stage. You don't see Seonghwa seated anywhere yet.
"And what are the starting bids on you, lovely?" a low voice asks, breath tickling your ear. You turn to look at the owner of the voice, his strong facial features almost as striking as his neatly-styled red hair. He's practically undressing you with his eyes, and you can't say you hate it.
"Whatever you've got to offer, pretty boy," you reply sweetly. He smirks, pleased with himself as one of his hands finds your waist.
"My friend says you're not as innocent as you look."
"Pardon?" you ask. The man turns you around, your back against his broad chest as his free hand reaches up to your ear. Before you know it, your earpiece is on the ground in front of you, crushed beneath a polished designer shoe. Looking up, you see that the shoe belongs to none other than Park Seonghwa. Of course they're working together.
You freeze as something cold presses to the exposed small of your back.
Fuck.
"One wrong move and you're done for, princess," the man with red hair says calmly, lowering himself back down to your ear. "Try to cause a scene and innocent people will pay the price."
You take a deep breath before nodding your head in submission. You slowly turn back around and watch as he returns his gun to his shoulder holster, his expensive blazer completely concealing it. No one around you sees the ordeal, too distracted and eager to spend their money. The man then puts his arm around your shoulders, leading you out of the auction room. Seonghwa follows close behind, making sure you aren't able to slip away. You have no idea if he is armed at this point in time.
You're led into a large meeting room at the very end of the upstairs corridor, the bright moonlight seeping through the open balcony doors and illuminating the glossy wooden table at the center of the room. You catch a glimpse of the pretty garden below the balcony before the man guiding you throws you to the floor. You can feel the bruises forming on your knees instantly.
You don't dare fight back yet—your training in hand-to-hand combat doesn't do shit when your opponents are armed with guns, of course. You would attempt it if he were alone, but with Seonghwa present and potentially armed, you'd rather feel the situation out.
God, Chan will never let you out onto the field again. He's probably losing his mind now that you've lost contact with each other. Not to mention the fact that you were busted before you even had a chance to get what you came here for. The auction is going to start any minute, and now you're certain there are other ATEEZ members in the auction room that are ready to claim the Cromer instead of you.
You're angry with yourself for not being more prepared with your own weapon, but your favorite handgun unfortunately didn't fit under your dress of choice. You sigh to yourself. At least you look good in it.
"Give it up, sweetheart. We know what's going on here," the man with red hair says. Seonghwa locks the door behind him before speaking.
"I saw your wolf tattoo, and I've seen only one other just like it. You're working with Bang Chan," he states, is emotions unreadable.
No. You had forgotten to conceal your waist tattoo since your dress fully covers it. You hadn't expected to completely remove your dress tonight. Rookie mistake. You should expect everything.
"All this over a tattoo?" You eye him, downplaying the situation.
"How brave of you to interfere with our operation by yourself," the other man comments, ignoring your previous sentence. "No back up here to save you, huh?"
"Oh, you don't really believe she's here alone, do you, San?" Seonghwa asks. Choi San. You recognize that name. Seonghwa comes over to you, a completely different aura surrounding him now. He's intimidating, gripping your chin with much more force than he had earlier. "Be a good girl and tell us where your friends are, yeah? Don't make things difficult." A chill runs down your spine at his threat.
"I'm not here with anyone," you state. It's the truth. Even though Chan had insisted he wait in his car nearby, you convinced him to stay and monitor operations from your base. If you don't make contact within the next hour or two, he'll know something is wrong and follow Seonghwa's location.
"Wrong answer, princess." He grips your hair harshly and you wince. "I have a hard time believing that they would put you in a situation like this without back up. Where are they?"
It's sweet of him to underestimate you, honestly. You got yourself into this situation, and you're sure as hell going to get yourself out. You're already halfway done formulating your escape plan. "I said they're not here," you answer again. He lets go of your hair with a hiss.
"It would pain me to ruin such a pretty face...I think we'll let the boss deal with you."
The boss? Chan told you that no one knows the leader of ATEEZ—it's safe to assume that anyone who's seen him hasn't lived to tell the tale. You're not sure if he'll have any mercy at all to offer you. But maybe these two still have some in them.
"No, please!" you plead, your fists balled up as they rest on your thighs. "If I tell you where they are, will you go easy on me?" You let your head hang low, looking at the floor. San lowers himself in front of you and you find his eyes. You blink, letting a few tears slip down your cheeks.
"Sure, doll face. We will." You look away from him to briefly meet eyes with Seonghwa. He still stands at full height, arms crossed as he looks down at you. Perhaps it's your tears making your vision blurry, but you swear his gaze softens at the sight of you. You look back to San, sniffling.
"You promise?"
Now, never ever would someone in their right mind trust a promise from someone like them. But you're not planning on following through with your own side of the promise, either. Two can play at this game. You would never jeopardize the safety of SKZ...you told Chan you could handle yourself and you meant it.
"Promise," San says. He's truly something else, radiating such strong and convincing charm. You would fall for his promise in a heartbeat if you didn't know who he really was.
As you slowly rise from your knees, San stands with you. "They made me do it," you confess, more tears spilling from your eyes and taking your favorite mascara with them. "They said they would kill me if I didn't," you whisper, looking away.
"It's okay, doll," San says, coming closer to comfort you. You flinch before he touches you. "Just tell us where they are, okay? We'll help you." You bury yourself in his chest, your frame shaking in his arms as you cry quietly.
Your best performance yet, if you say so yourself.
After a long minute in his embrace, you begin to pull away. In the process, you grab the gun out of San's shoulder holster and hold the barrel to the center of his chest. He curses under his breath, raising his arms in defeat. You slowly step backwards, turning your aim to Seonghwa as a warning not to try anything, and then returning your aim to San. Seonghwa makes no attempt to grab for anything, so now you know for a fact that he is unarmed.
"I told you the first time that there's no one here with me." You smile. "But it's nice to discover that you both have a heart."
"Tell Chan we said hi," Seonghwa replies, irritated.
"Of course, it would be rude of me not to. It's truly been a pleasure, boys." You give Seonghwa a wink. "We'll meet again, right? Maybe you can introduce me to your boss next time."
You've backed up far enough to step onto the balcony, assessing the situation above and below. The garden below is deserted now that the auction has started, but it's a far drop to the ground. There is another balcony above you, but it seems a bit too high for you to escape to. You're trapped, so you're going to have to pull this off fast to avoid getting hurt.
All you can hear is the sound of your own heartbeat as you throw the gun over the railing into the garden. If you slip up, they could get their hands on it again, and you cannot let that happen. You'll fight the real way if you must.
As soon as it leaves your hands, the men launch at you. You quickly dodge them, ducking under San's punch and managing to sweep Seonghwa's leg, knocking him to the ground. Now that they're both on the balcony, you run back inside, shutting the french doors and locking them behind you. You know it will barely do anything to set them back—they could easily break them down if they wanted to. Through the glass, you watch as San pulls Seonghwa off the ground and looks at you. He doesn't make an immediate effort to get inside.
Is he letting you go?
You shouldn't wait around any longer to find out. You blow him a kiss before taking your exit out into the main hall.
But after stepping out, you see why they let you go...
