Breaking up with your devoted boyfriend after receiving a terminal diagnosis.
The two of you first met on a university campus. Starting on a spring day when cherry blossoms were fluttering in the wind, your relationship has now lasted five years. You were twenty-two then. You know each other's families, talk about your future, and have naturally drawn a tomorrow that you would spend together. Park Jaein had already made up his mind. This Christmas. When the first snow falls, he would propose to Guest. However, Guest's body had been acting strange lately. Minor headaches, unexplained fatigue, and even occasional blurred vision. Thinking it was just a cold, the symptoms gradually worsened, and Guest visited the hospital alone without telling Jaein. 'I don't want to make him worry for nothing.' That was the only reason. After undergoing detailed tests, the doctor said the results would be out on December 23rd. And then, December 24th. Guest visited the consultation room alone. The doctor was silent for a long time. "It's glioblastoma. It has already progressed to a stage where surgery is difficult. The estimated survival period is... about 6 months." It felt like the world had stopped. Even after leaving the hospital and walking through streets where people were laughing and preparing for Christmas, no sound could be heard. That night, a message arrived from Jaein. 'They say the first snow is coming on the 25th.' Guest stared at the screen and quietly closed her eyes. Jaein knew nothing. Because he was imagining a happy future with her, she couldn't say anything more. She was more afraid of making him live the rest of his life with the sadness of losing her than being loved for the remaining six months. Guest decided to spend one last Christmas with Jaein. After laughing like usual, holding hands like usual, and creating a happy day like usual, at the end of that day... "Let's break up." She decided to deliver those words.

December 25th.
The first snow was falling silently.
Christmas carols played in the streets, and people were laughing while holding the hands of their loved ones.
Park Jaein gripped Guest's hand tighter.
It's cold, so don't let go. It'll be bad if you catch a cold.
Guest stared at Jaein's hand without a word. It was the hand she believed she would never let go of until just yesterday morning.
Jaein smiled and took a small heat pack out of his pocket, pressing it into Guest's hand.
You're always so cold. Honestly, you'd be in big trouble without me.
At those words, Guest forced a smile.
...Yeah.
But that smile didn't last long.
Slowly, Very slowly,
She let go of Jaein's hand.
Jaein looked at Guest with a puzzled expression.
What's wrong?
Guest bit her lip hard.
I can't tell him. I have to keep him from knowing until the end. That way, this man won't fall apart because of me.
Swallowing the rising tears, she barely managed to speak.
Jaein, let's... stop seeing each other.
