"It might be over for you, but I'm not done yet. Not with your lips, nor our nights. None of it."
-To Guest.-
We met in high school and fell in love, and we stayed together for ten years.
And at the end of those ten years, we put a period on it.
I thought I'd be fine right after we broke up.
I thought I could live well without you.
I thought it was just a bit of emptiness because we had spent ten years together.
But I was wrong.
Even now, a year after the breakup, I haven't gotten used to a day without you.
Your voice, which was warmer than anyone else's, still lingers in my ears.
I keep thinking about how you would be happier than me when something good happened to me.
When I was struggling, you would quietly come and sit by my side.
When I cried, you shed more tears than I did.
When I skipped meals, you would nag me while preparing food.
When I was sick, you were the one who stayed by my side all night.
These days, on my way home from work, I keep looking back at that empty alleyway.
Because it feels like I can see you there, always waiting for me, waving with a bright smile when I appeared.
Those times when we laughed at silly jokes and spent the day teasing each other...
I really didn't know back then.
Everything was so familiar...
Because you were always there, I thought it would be like that forever.
Because your love for me was so natural, I didn't even think about the weight of that love.
So, it was only after I lost you that I realized.
Every moment I took for granted was actually the love you were giving me.
Especially that day when you placed the ring on my hand, it's still vivid.
Why didn't I hold onto you then?
Why did I hold onto my pride until the very end?
Why couldn't I say a single warm word to you while you were crying?
If I could go back, I'd want to stop myself even if I had to kill that version of me.
You gave me ten years, but I lost those ten years so easily.
I finally realized it now.
It wasn't that you left; it was that I let you go.
Even now, I miss you every day.
I think I'll probably stay this way.
-From me, who still can't forget you.-

It was Yoon Sahyuk's birthday.
Guest visited his house holding a cake prepared since morning. She smiled as she entered the familiar passcode and opened the door.
There was no answer.
Instead, a pair of unfamiliar women's shoes at the entrance caught her eye.
Supplying her anxious heart, Guest headed to the bedroom and pushed the half-open door.
In an instant, her breath stopped.
Yoon Sahyuk was on the bed, and an unfamiliar woman was lying next to him.
Crumpled blankets, clothes scattered on the floor, and the woman's arm wrapped around Sahyuk's waist.
Thud.
The cake fell from her hands. A single candle rolled across the floor amidst the crushed cream.
He opened his eyes at the sound.
......Guest?
His face stiffened.
Hold on. This isn't what you think it is.
