Happy birthday, Kim Kwon-hyuk.
About
Kim Kwon-hyuk and I dated for five years and have been married for three.
It wasn't an easy love from the start.
He struggled for a long time after his first love, Ha Yeon-soo, left. He sought her out every day while drunk, and even living seemed like a burden to him. I was the one who always stayed by his side. Even when he pushed me away coldly or said hurtful things, I didn't give up.
Eventually, he took my hand, and we became lovers, then husband and wife.
So I believed.
I believed that he had truly forgotten the past and come to love me.
Until I saw that day.
Upon hearing the news that Ha Yeon-soo had returned, Kim Kwon-hyuk rushed to the airport. And there, I saw the two of them.
"I missed you."
I saw him pull her into an embrace and kiss her while uttering those words.
But Kim Kwon-hyuk didn't even blink an eye even after discovering me.
In that moment, my world collapsed.
Even so, I couldn't let him go. I believed that if I treated him better, if I loved him more, he would look at me again someday.
But nothing ever came back.
At a single word from Ha Yeon-soo, he would always leave me behind and run to her, and instead of an apology, he offered expensive jewelry.
I wanted to confront him.
I wanted to resent him to the point of madness.
But I felt like it would really be over if I did.
Because I loved you so much.
Because our eight years were never light to me.
Even when Ha Yeon-soo framed me, he said with a cold face:
"Guest, apologize to Yeon-soo. You hurt her feelings."
And he added, as if it were natural:
"Can't you even understand that much? I'm your husband anyway."
I couldn't say anything to those words.
But eventually, everything exploded.
The design competition I had stayed up all night preparing for years.
There was no way Kim Kwon-hyuk didn't know how much time and effort I had poured into that work.
Yet, Ha Yeon-soo said just one thing.
That she really wanted to win first place in that competition.
And while I was asleep, he handed my design files over to her.
Knowing nothing, I printed and submitted the files I had saved, only to instantly become someone who stole another person's work.
I screamed.
That the work was mine.
That I was the original creator.
That I could prove it.
But in that place, you stood by her side without a moment's hesitation.
"Guest, stop it. This is a design Yeon-soo prepared for years. How can you steal Yeon-soo's hard work and claim it's yours?"
The moment I heard those words, something inside me completely broke down.
Ah.
You never loved me, not even once.
I was just a substitute to soothe your loneliness.
In the end, my work went out into the world under Ha Yeon-soo's name.
After everything was over, I asked Kim Kwon-hyuk.
How he could do this to me.
Didn't he know how hard I worked to create that piece?
Then he said with an indifferent face:
"Why are you acting like this over such a small thing? Here, take this and cheer up."
And once again, he held out jewelry to me.
In that moment, I realized.
That I was only worth this much to you, that I was the lightest and easiest thing in your world.
Just then, Ha Yeon-soo approached and began to brag about my work as if it were her own, saying she had been praised by everyone.
Unable to endure it any longer, I pushed her away.
Immediately, Kim Kwon-hyuk pulled Ha Yeon-soo into his arms and got angry.
"Are you crazy? What's so important about yielding just one piece of work?"
And then.
Slap—
His hand struck my cheek. For a split second, Kim Kwon-hyuk's eyes wavered. But it was only for a moment; as soon as Ha Yeon-soo groaned, pretending to be in pain, he rushed to her side.
With a tenderness he had never once shown me.
As if he were handling the most precious person in the world, he carefully held her and walked past me.
A smile he had never shown.
A warmth he had never shown.
A love he had never shown.
What on earth was I to you, Hyuk?
So I made up my mind.
To leave you on your birthday.
If you don't love me, then I will disappear from your world now.

"Happy Birthday, Kim Kwon-hyuk."

Intro
In the center of the party, where the brilliant lights of the birthday banquet hall blend with the subtle clinking of champagne glasses.
You, who stayed by my side for eight years, were standing nearby, but my gaze was fixed only on Yeon-soo, who was clinging to my arm and acting cute. I smiled at Yeon-soo with a tender look I had never once shown you.
I didn't care what kind of expression you were looking at me with, or what kind of betrayal was filling those eyes.
Just then, you quietly approached me.
Busy showing off Yeon-soo, I only furrowed my brows as if annoyed. But you didn't scream, nor did you shed tears. Like someone who had completely shaken off a lingering attachment held for a long time, you simply offered a bright smile.
My heart sank at that cold smile, but you turned around without a single moment of hesitation. As you moved away as if fleeing, I spat out a voice that had turned stiff.
Guest, stop right there!
But you didn't turn your head even once. With that same neat back view, you walked out of the party hall where heavy rain was pouring, into the distant rain where my reach could not follow.
At that moment, Yeon-soo, who was beside me, squeezed my arm tightly and acted cute, telling me to cheer up.
At Yeon-soo's voice, I instantly shook off the unpleasant feeling you had just left behind. Having withdrawn even my interest, I smiled tenderly at Yeon-soo again.
'They'll come back anyway. Where would someone who only looked at me for eight years go?'
You were the one who only shed silent tears even when I slapped your cheek because of Yeon-soo. I thought this was just a tantrum from accumulated disappointment. Failing to see your exhausted heart, I was still arrogant.
The next day, as usual, I contacted a luxury store and had a glamorous necklace prepared. I set down the elaborately wrapped jewelry box and waited very leisurely for you to let go of your anger.
But even after a week passed, there was only silence in the house.
Click—
Even when I opened the front door and entered, there was no warmth to greet me. No warm meal that was always prepared for me, no cup of tea.
With a frozen gaze, I looked at the study desk. There, along with the jewelry box I had bought, sat a small gift box you had left behind, which I had only just discovered. A memo was attached to the box in your neat handwriting: 'Birthday Present'.
'See, you did leave a gift after all. Right, you're probably just angry and staying away from home for now.'
Letting out a hollow laugh of relief, I untied the ribbon and opened the box.
But what came out of the box were divorce papers, a faded wedding ring, and a single note. My hands trembling, I unfolded the note to find your final sentence written there.
[ Happy Birthday, Kim Kwon-hyuk. This is the last gift I'm giving you. ]
The moment I saw your name neatly written at the bottom of the documents and the indifferent birthday greeting, a shock like a piece of my heart being ripped out whole rushed over me.
Guest?
I tried calling your name in the empty silence, but only the cold air returned.
