Present, Y/n POV
My knees go weak & I plop heavily down to the sofa.
I don't know what to say anymore. The betrayal hits me too hard.
"Please don't listen to her Y/n ah. She's lying! I love you & only you. Otherwise, why would I ask you to marry me?" Jin kneels down in front of me & pleads.
"Why didn't you tell me anything? You never told me that you suffered from depression. Never told me that you met Jin before. If you had been honest with me about your feelings, I'd probably back off." I turn to Seoyeon, still not believing that she's kept all those secrets from me.
"It wouldn't matter. If you broke up with him, he would find another replacement & I would still be the third person in the relationship. I'd rather you become his girl friend, that way at least I can monitor your relationship up close." She answers flatly.
"Shut up! Ignore her Y/n ah, she's crazy! Please believe me, you're the only one for me." Jin says frantically.
"Crazy? I'm crazy because of you Jin! If only you didn't say that you'd marry her, I wouldn't have planned all this!" She yells as she flings her arms in the air.
"What? What do you mean?" I stare at her, scared of what else she's going to reveal.
"God, you're so stupid, you didn't even know what hit you." She chuckles evilly.

Flashback, Seoyeon POV
Our affair started that day after we kissed. I had never once pushed Jin to break up with Y/n, because I believed that one day he would realize that I was the only person who could understand him completely. So it came as a shock to me when he told me that he was going to marry Y/n.
"Seoyeon ah, remember Jungkook? My friend I told you about?" He asked one night.
"Yeah, the one who helped you a lot when you were in the States?" I answered disinterestedly as I folded the laundry.
"I'm going to ask him to be my best man."
The shirt I was folding dropped to the bed.
"Bestman?" I turned to him, panic precipitating in my mind.
"Yes. I'm planning to marry Y/n." He walked closer & sat down in front of me, looking up at me with an unreadable expression.
"Are you fucking kidding me?! If you're going to marry her, then what are you doing here?!" I shoved his shoulders & stormed out of the room.
"You know I need her. She's the perfect spouse for me." He followed me out.
"Why? Because she's not broken like me? Because she has a successful career & I don't? I thought you loved me Jin! Are you just using me all this time?!" Tears rolled down my cheeks as my scream got more & more hysterical.
"You know I love you! You're the only one who knows who I truly am. But my family & friends won't approve of you, that's just how it is!"
His words stabbed me right in the center of my chest.
"Fuck you Jin. Get out of my house, right now!" I pointed at the door & yelled at him.
"Please Seoyeon ah. I'll still take care of you like usual. I can't live without you." He hugged me tightly from behind & nuzzled my neck. I could feel his warm tears seeping through my T-shirt.
I should've let him go right then, but I desperately held onto him.
I turned around & cradled his face.
"Promise me that you won't leave me alone." I leaned my forehead on his & muttered.
"I promise." He said, before pulling me in for a deep kiss.
I can't let him marry Y/n. I have to do something.

My chance came that night in Vegas.
"Now it's time to have some fun!" I clapped excitedly & handed her a tequila shot which I had secretly doused with GHB.
"Aren't we having fun already?" Y/n giggled as she downed the shot of tequila that I gave her.
I smiled inwardly seeing her swallowing the drink.
My initial intention was to trick her into sleeping with some random guy & then guilt-tripped her later so that she'd break up with Jin.
"No no no. It's not a bachelorette party without some flirting with random guys." I said as I scanned the club for a target.
And then, I unexpectedly saw a familiar face in the crowd.
Isn't that Jin's friend? What's his name? Jungkook? This will be interesting.
"See that guy over there? The one in black shirt & black pants? Go dance with him." I said as I pointed at Jungkook.
"Yaaa, I'm not doing that. That would make me unfaithful to Jin." She refused as she glanced at the diamond engagement ring on her finger.
"Come on. All you have to do is dance with him. It's only for fun. Besides, what happens in Vegas, stays in Vegas. Right girls?" She looked at the other girls for support.
"Ok ok fine. I'll do it, but promise me you won't tell Jin about this. Pinky promise." She extended her pinky finger at me & I hooked it readily.
"I promise. Now go!" I pulled her up & slapped her butt.
"Ya, are you sure she'd be alright?" One of our friends asked in concern.
"I'll go check up on her." I abruptly stood up & rushed towards the direction Y/n went to.
I watched Y/n & Jungkook from afar, and prayed that my plan would work.
No, I have to make sure they really do it.
"Excuse me? Can I have two shots of vodka, please?" I hollered at the bartender.
Luckily, I brought two extra pills.
I put the pills in the glasses, waited for them to dissolve, then called the bartender again.
"Tonight's my friend's bachelorette party. She's right over there with his boy friend. Can you please deliver these drinks to her? Just tell her that they're on the house. Thanks." I smiled at the bartender & gave him a hefty tip.
A satisfied smirk lifted my lips as I saw Y/n & Jungkook drank the shots in one go.
I followed them for the rest of the night, until they left the club & went on a taxi together.

Present, Y/n POV
"My plan had worked, but I didn't expect that you would actually go & marry him. You always deliver beyond what was expected & this time it was no exception." She laughs out loud.
My whole body goes numb as I immediately turn to Jin.
"W-What? Married? What are you talking about?" Jin's eyes widen in shock as he looks straight at me.
"Omg, so you planned all this since the beginning. Hyung, she drugged us! Y/n's & my marriage was an accident." Jungkook gasps in shock.
"Oh really? If it was an accident, why didn't you divorce her right away?" Seoyeon raises her brow at him.
"What the fuck?! You got married to Jungkook on your bachelorette's night? Oh God, here I am agonizing because I slept with Seoyeon. But you're actually much much worse than me." Jin scoffs in disbelief.
"I didn't marry him on purpose! Didn't you hear her? She doused my drink with GHB so that I would lose my consciousness & do stupid things! I was terrified when I found out the next morning." I cry.
"You should've said no to flirting with random guys in the first place! You shouldn't have drunken too much! I thought you were better than that Y/n." Jin yell at you frustratedly.
"Kim Seokjin, how dare you? You cheated on me with my best friend for one year. One whole fucking year!" I scream back at him.
"Fine, let's say I believe that you didn't mean that to happen, but what about you Jeon Jungkook? If it was a mistake, why didn't you divorce her when you found out that she's my fiancée?!" Jin glares at Jungkook & pushes his chest hard.
"What else? It's because he likes her of course. He even agreed to help me break you two up." Seoyeon rolls her eyes, seemingly enjoying herself watching all the drama unraveled.

"So you're in it together with her?" My head hurts, I've completely lost it now. Why does my once plain & simple life end up like this? Why are there so many secrets?
"How could you do this to us? I trusted you!" Jin motions to grab Jungkook's collar.
"It's not what you think. I initially refused to divorce her to protect you hyung, because I thought she was a two-faced gold-digger, because her action that night in Vegas didn't match the image she has right now. I forced her to break up with you by offering her money & threatening to reveal what she did that night, but she wouldn't budge. So I realized that maybe she just made a mistake that night & this is her true self. She truly loves you, not your money. I was going to divorce her, but.."

Flashback, Saturday morning, Jungkook POV
Finally, all of this will come to an end soon. I hope she & Jin hyung will be happily married for a long time. Unlike me.. Wtf Jeon Jungkook? Your marriage was an accident, there's no need to feel melancholic about it. Just sign the papers & forget about her.
I shook my head to get rid of my thoughts & continued reading the newspaper in my hand.
My peace was soon disturbed by an incoming call from an unknown number. I immediately rejected the call & focused back on reading, but the call came again & again until I had no choice but to answer it.
"Hello? Jeon Jungkook ssi?" The female from the other end said.
"Yes, this is he. Who is this?" I answered disinterestedly.
"I'm Kang Seoyeon. You probably don't know about me, but I know a lot about you. Including your marriage to Y/n." She had completely captured my attention now.
"Who are you? How do you-"
"Let's meet face to face & talk about it. I'll be waiting for you at Hollys Coffee in Gangnam in fifteen minutes. See you soon." With that, she hung up the call.
"Who the hell is she?" I stared at my phone in bewilderment.
10:24 AM
I still have some time before I need to meet Y/n at the lawyer's office. Let's see what that woman wants to talk about.
10:37 AM
I anxiously waited for her in the cafe, myriads of thoughts running through my mind.
"Jeon Jungkook, nice to finally meet you." A woman suddenly sat down on the seat in front of me.
I observed her face & I was pretty sure that I had never met her before.
"You must be confused. Let me introduce myself. My name is Kang Seoyeon & I'm Y/n's best friend." She said as she took off her sunglasses & smiled at me, her smile not reaching her eyes.
"Are you here to convince me to divorce her? Don't worry, I'm going to do that in less than 2 hours from now."
"Actually, I'm here to ask you to do the exact opposite. I want you to stay married with her & convince her to leave Jin."
"What? I don't understand."
"Friday night at the club, you saw Jin with a woman, right? That woman was me. I'm having an affair with Jin. We love each other." She said matter-of-factly.
I was at loss for words. Her confession had stunned me completely.
"Wait, you said you were Y/n's best friend? How could you have an affair with her fiancée?" I was surprised at how angry I was towards her.
"Well, you're Jin's best friend yet you're married to his fiancée." She scoffed.
"Oh God, this is so fucking messed up." I pushed my hair back in frustration.
"You want to protect Jin, right? Imagine if he finds out about your & Y/n's betrayal, he would go back to his old self-harming self. Do you want that to happen?"
"Of course not! But if Y/n leaves him, he won't be happy either. How do you know all of this anw? Even Y/n didn't know about hyung's dark past." I stared suspiciously at her.
"I told you, we love each other. He told me things that he'd never told Y/n. So don't worry, he'll be happier if she leaves."
"Why should I play along with you? Y/n & I can just get a divorce quietly & pretend that nothing has ever happened. Jin hyung won't know." I scoffed.
"Sure you can do that, but if you do, I'll send the evidence of your marriage to every one she knows. Her parents, Jin's parents, her friends, every one. And I do have pictures for proofs, in case you don't believe me."
She took out her phone & showed me the screen.
My eyes widened as I saw pictures of Y/n & me kissing & hugging in that club. Our bodies pressed hard against each other, our wide grin plastered on our faces, like a couple in love.
"Do you think she'll be able to handle it?" She smirked.
"Gimme that." I tried to snatch the phone away from her but she moved it out of my reach.
"Uh uh, you have to agree to go along with my plan first, then I'll erase the pictures."
"Omg, why are you so evil? What exactly did she do to you that you'd do something like this to her?!" I banged my fist on the table & glared at her. My heart ached for Y/n who was so innocent that she hadn't had any idea about the evil things her supposedly best friend was doing behind her back.
"I wouldn't do this if she wasn't getting in the way between me & Jin. Wait.. You like her, don't you?" Her eyes lit up in realization.
"No, I don't." Feeling like I'd been found out, I quickly averted my gaze.
"You do. Omg.. So this should be perfect for both of us, right? You get Y/n & I can be together with Jin." She exclaimed excitedly.
"I-" I was about to reject her but I figured I should've pretended that I was on board with her plan before I could find a better alternative.
"Alright, I'll do as you say, but you need to erase those pictures now." I said.
"Promise?"
"You have my word." I nodded.
"I don't trust you. Call her now." She frowned.
Cold sweat drenched my forehead as I contemplated about what to do.
"See? You can't even do it." She scoffed & folded her arms in front of her chest.
"Fine, I'll call my lawyer." I braced myself & dialed my lawyer's number to cancel my appointment this afternoon.
"Done. Now give me your phone." I extended my palm towards her.
"Knock yourself out." She handed me her phone & I quickly deleted all of the incriminating pictures.
As I scrolled through her gallery, I saw a lot of her & Jin's photos together. He was smiling at the camera in most of them.
So she really was telling the truth about her & Jin.
"Are you done staring at my pictures?" She asked all of a sudden, snapping me out of my thoughts.
"Let's keep everything to ourselves for now. You don't tell Jin hyung about my marriage & I won't tell Y/n about your affair. I'll try to convince her to leave him."
"Great. Nice doing business with you. Let me know if you have succeeded in convincing her to leave him. Remember your deadline is the day of their wedding, which is next week. I'll talk to you again soon." She rose from her seat & left the cafe, leaving me alone with my tumultuous thoughts.
What should I do now? Should I talk to Jin hyung? Or maybe it would really be best if he broke up with Y/n. Then, I can.. No! What are you thinking about? You shouldn't be swayed by Seoyeon.

Present, Y/n POV
"That's why I cancelled on you that day. I'm sorry, I shouldn't have gone along with her plan. I should've talked to you & Jin hyung right away." Jungkook explains, his tone full of remorse.
"Kang Seoyeon! You crazy bitch! How could you be so evil? I can't believe that we all fell into your trap." Jin yells at Seoyeon.
"Fell into my trap? I didn't force you to have an affair with me. You did it on your own will, knowing full well that you'd betray Y/n by doing that. Now you're putting all the blame on me?! I just wanted to protect what's mine & as far as I know, you are mine!" She shouts back.
"You're being delusional! I'm not yours, never was & never will be!" Jin's eyes are red with fury & he looks like he's about to pounce at Seoyeon.
I don't even know what to say anymore. All their words just bounce off me like a rubber ball on a concrete wall. Their betrayal has extended far beyond what I could ever imagine.
"Hyung, stop it. Please. Can we all calm down for a sec?" Jungkook notices my blank expression & pulls Jin away from Seoyeon.
"You. You like Y/n, don't you? That's why you refused to divorce her. To protect me my ass. You must want her for yourself! You backstabbing son of a b*tch!" With that, Jin throws a punch at Jungkook & it lands right on his cheek.
"Stop! Just stop it!" Finally having enough, I scream my lungs out.
All of a sudden, the room falls silence as everyone's head turns to me.
I slowly rises from my seat & moves my right hand towards my left.
Jin's eyes widen in fear & he rushes towards me right away.
"No no no. Please don't do that. Please don't leave me. I can't live without you." He says as he holds my hands tightly.
"Let go of me Jin. I can't do this anymore. I won't be able to recover from this." I push his hand away, take off my engagement ring, & put it in the center of his palm.
"No Y/n. Please. I can't live without you. Please give me another chance. I'm so sorry, I'll do anything to make up for my mistakes just please don't break up with me. Please." He kneels down in front of me & grabs my hand.
"I can't Jin." I say as I swallow the sob down my throat.
"You still have us." Seoyeon suddenly mutters.
"Us?" I look up at her.
"I'm pregnant. With Jin's child." She calmly says, like it's normal. Like her words don't shoot through my heart & explode in there, breaking it into a million pieces.
That's it. That's what breaks me. I drop down to the floor & howl a painful cry that doesn't even sound like me.
It's officially ended. My life as I know it has officially ended.
