My fiancé is one of the country's top neurosurgeons.

One day, he discovers that his childhood sweetheart has been diagnosed with cancer and only has a month to live. He wants to spend this time with her, so he feeds me a newly developed memory-wiping drug to make me forget him for a month.

During that time, he throws his childhood sweetheart a wedding and goes on a honeymoon with her. As they stand amid an ocean of flowers, they vow to be together in another lifetime.

One month later, he kneels before me in the rain. Tears stream down his face as he says hoarsely, "The drug's effects were only supposed to last for a month. Why have you permanently forgotten me?"

Nathaniel Mercer's first love, Jolene Lanier, was back in the country.

He poured a cup of chamomile tea without thinking and passed it to me. "Jo has terminal cancer. She's got only a month to live, and wants me to stay with her until the very end."

His face was calm and unreadable.

I frowned. "Shouldn't she be with her family? Why you?"

Jolene was Nathaniel's childhood sweetheart, and even after they broke up, he always said they were still like family.

I'd been jealous of her more than once. And now, here we were, days away from our wedding.

Nathaniel ducked his head, his eyes skirting away from mine. "Mr. and Mrs. Lanier died in a car accident recently. Now she's all alone."

"You feel sorry for her," I said, catching the note in his voice.

"It's just a sad situation. That's all." He shrugged, then tapped my nose playfully. "Are you nervous? You're about to be my bride."

"Please." I rolled my eyes. "Not yet."

"Soon enough." He smiled, then turned earnest. "You'll be my only wife. I love you forever."

Nathaniel was quiet and reserved, never one to pour out romantic words. Even his love confession was understated. He shaped his EEG charts into a heart and showed it to me.

But now, out of nowhere, he promised to love me forever.

I leaned into him and asked if he'd help me pick our wedding welcome photo.

He pulled me in a little tighter and said, "You decide. The wedding's coming up, and I've got to hand off my work at the lab."

Nathaniel went to change his clothes. He'd always been careful about his appearance. I used to get lost just watching him.

But this time, when he walked out, his shirt was barely tucked in, and his socks didn't even match.

I pressed my lips together and kept quiet. I headed downstairs, flagged a cab, and trailed behind him at a distance.

His car sailed past the lab without slowing down, heading straight for the hospital.

I didn't follow him any further. He was probably going to see Jolene.

Nathaniel came home in the middle of the night. The lights were off, and I was curled up on the couch, watching him without a word.

He flipped the switch and froze when he saw me sitting there. After a moment, he started walking slowly toward me.

"You already knew?" he asked, his throat tight as he swallowed.

I nodded.

We'd spent five years together, long enough to know each other inside out. The way he blurted out his promise, his shirt half-untucked, told me everything. He was guilty and panicking.

To Nathaniel, I'd always been the carefree one. Me, sitting there dead silent in the middle of the night? That wasn't like me at all.

We both knew something was wrong.

He eased down, leaning against me, and placed a test tube filled with drugs before me.

"It breaks my heart to see Jo lying in that hospital bed, all hooked up to tubes," Nathaniel said, looking completely at ease. "I promised Mr. Lanier I'd take care of her."

A cold dread seeped into me, stiffening my limbs. "So you're staying with her until the end?"

He gave a quiet hum in reply.

Silence settled over the room. After a beat, Nathaniel reached out hesitantly, his fingers brushing the test tube.

"What's this?" I asked, my voice tight as I met his eyes.

He looked away before answering, his tone soft. "Jolene needs me for the next month, Mae, but I know you'd never agree to let me go. I still want to marry you when this is over, so I need you to forget me until then. Once I'm back, we'll have our wedding like we planned."

Then I realized. This had to be the memory-wiping drug Nathaniel had recently developed.

"You want me to forget you?"

I was stunned. The man I loved was leaving to give himself completely to someone else.

"No! Mae, I'm not saying you should forget me forever. It's just for a month," Nathaniel said, his voice still gentle, even if the request was absurd. "I'll come back to you after that."

I sat there in a daze. The sting at the corners of my eyes betrayed how I felt. Five years together, and this was all I got.

With a self-deprecating laugh, I said, "This is a brand-new drug. It hasn't even been tested in clinical trials yet. What if something goes wrong? What if I forget you for more than a month? What if it harms me?"

Nathaniel paused for a moment as he worked the test tube cap loose, but soon after, he continued without hesitation. The cap gave way with a soft pop.

"My drug is perfect. I'm the top neuroscientist in Halyndra." He held the test tube to my lips. "I'll come back for you in a month. Then we'll get married and be the happiest couple alive."

I turned my head away. "Why would I say yes? I'm not some trash bin for garbage. I don't just take whatever filthy thing gets thrown at me. You're clearly cheating, so don't even think about coming back!"

"I'm not cheating!" Nathaniel said, his agitation rising. "She's suffering! How can you talk about her that way?"

The man I loved with all my heart had just crossed a line, choosing to defend another woman instead of me.

Nathaniel took a deep breath and held up the test tube. "Mae, everything will be fine in a month."

Out of nowhere, he stood and forced me back against the couch. His fingers clamped around my jaw, squeezing my cheeks until my teeth pressed into the inside of my mouth.

Then he jammed the cold test tube between my lips. The liquid slid down my throat, sharp and bitter.

During the struggle, some of the drug went down the wrong way, and I started coughing hard. But Nathaniel didn't back off. If anything, he pinned me down even harder.

I thrashed wildly and drove my foot into his stomach. He grunted, and for just a second, his grip loosened.

I tried to turn my head and spit out the drug, but he grabbed my hair and yanked me back, forcing the liquid deeper into my mouth.

The test tube cut my tongue, and the metallic tang of blood soon replaced the bitter taste. Tears sprang to my eyes from the pain, blurring Nathaniel's face.

The second the last drop was gone, he released me. I shoved my fingers down my throat, trying to make myself throw up, but only bile came up, scorching my throat.

Choking, I fought to breathe through ragged, wheezing gasps.

I trembled, clutching my head as searing pain pulsed through my skull over and over, like something was trying to burst out of my temples.

The agony slowly took over, and my thoughts began to slip away. My limbs went weak, giving out beneath me as my vision turned hazy.

The only sound I could make out was Nathaniel's soft voice. "Mae, I really do love you. But Jolene is dying, and no matter what, I have to stay with her until the end. Forget me. Forget… Nathaniel Mercer."

His voice faded more and more, drifting out of reach, until I slumped sideways onto the couch. Those last two words lingered in my mind—Nathaniel Mercer.

Who was that?

My phone chimed.

"Hello?"

My eyes were barely open, my head still foggy with sleep.

"Maeve Yule! What are you doing?" It was Yelena Anderson, my best friend. "I flew seven hours just to be your bridesmaid, and now they won't even let me into the hotel! And the bride is… Jolene Lanier? Who's that? What kind of game are you and Nathaniel playing? Are you messing with me?"

I shot upright, suddenly wide awake. "Who's getting married?"

Yelena sounded even more shocked than I felt. "What do you mean? Isn't today your wedding with Nathaniel?"

A cold sweat broke over me, and I retorted, "Who the hell is Nathaniel? You know I've always been single."

"Cut the crap, Maeve! You've been dating him for five years. There's a wedding photo of you two hanging on your damn wall!" Yelena sounded completely fed up.

I bolted out of bed and tore through my home, but there was nothing. No sign that a man had ever set foot in here.

"It's just a portrait of me on the wall," I snapped. "Seriously, I don't even own a double bed."

"No freaking way! Hold on. I'm on my way."

Yelena hung up before I could say another word.

The second she stormed in, she started yelling at me, convinced I was pretending to have amnesia just to screw with her. But then she looked around, and her face went blank while she kept muttering, "No way."

"I'll prove it to you!"

Yelena suddenly remembered that she had joined Nathaniel and me at our wedding photo shoot and taken some candid photos that she posted on Instagram.

In the photos, I was wearing a white wedding dress, smiling brightly as I held the arm of a good-looking man in a black suit and gold-rimmed glasses.

I went completely still. I didn't know the man in the picture. His face meant nothing to me, but for some reason, tears started pouring down my face. I brushed them away, and that was when it hit me.

"Leni! Do I have a long-lost twin sister or something? Is my little sister actually the one getting married?"

Yelena let out an annoyed sigh. "Are you two fighting again?"

I grew agitated. "I mean it! I honestly don't know any Nathaniel."

Yelena gave me a long, searching look, her concern deepening. "You're not actually losing your memory, are you? Did you hit your head or something?"

She snatched my phone and scrolled through my contacts, but there wasn't any Nathaniel listed. Out of ideas, she called him herself.

The line picked up, and a soft voice answered, "Hello?"

"Nathaniel, what the hell is going on?" Yelena snapped. "Mae says she doesn't know you! And now you're marrying someone else?"

Nathaniel paused briefly before asking stiffly, "May I ask… who is this?"

Yelena shot to her feet, yelling, "Nathaniel! What kind of bullshit are you trying to pull? Don't act like you don't recognize my voice!"

"Wrong num—" he started, but a frail woman's voice cut in between harsh coughs. "Who is it, Nate?"

"It's nothing… Just a wrong number," Nathaniel replied, flustered.

Before Yelena could say a word, the line went dead with a series of beeps. Nathaniel had hung up.

"This isn't right." Yelena bolted out the door without hesitation. "Stay here. I'll keep you posted."

She was determined to figure things out, but I couldn't have cared less. Strangers had never been my thing.
