While on duty, her fingertips trembled as she saw a familiar name on the admission list she was mindlessly flipping through.
After a brief hesitation, she rushed over and stopped in front of the hospital room door.
She opened the door without knocking. Guest was lying on the bed, a pale and gaunt silhouette.
In that moment, the emotions Kang Yuyeon had been suppressing exploded.
She had lived like someone who didn't know how to cry... but impossibly, her lips were trembling.
It was the first time in front of you. Both revealing her emotions and crying.
She looked down at you and spoke with a trembling voice.
Why didn't you tell me?
You raised your head at the sound of her voice.
She wasn't the Kang Yuyeon you knew. She was always cold, unshakable, yet that person was crying in front of me.
My heart sinks. After staring blankly, I slowly raised my hand and wiped the corners of her eyes.
It was a face I had never seen before. I wanted to hide it, but seeing her expression so broken made me feel even more sorry. My voice shook.
Yuyeon, please don't cry... okay?

Her breath seemed to stop at your words. Barely managing to keep her legs from giving out, she squeezed her eyes shut.
Only now does it fully sink in why you pushed her away so hard.
'You were in pain, you were scared... that's why you kept me away.'
She realized only then that the choice you made to protect her ended up hurting her the most.
She quietly approached the bedside and placed her hand over your trembling back of the hand.
As if she would never let go again, she spoke while gently stroking it.
I won't leave you alone again.
In the past, before Kang Yuyeon and you started dating.
After finishing work at the hospital, she entered a familiar cafe.
Always the same seat, the same menu. She didn't pay much attention, but the part-timer who always quietly handed over her coffee was strangely memorable.
You knew her so well that she didn't even need a buzzer, and the brief eye contact shared occasionally lingered in her mind for no reason. That day, she suddenly felt like striking up a conversation.
I'd like to try something other than an Americano today.
It was the first time. Aside from ordering, she was the one to speak first.
The person who always took her coffee in silence was making eye contact today.
She had a cold impression, but her voice was softer than expected. I hoped my flustered state didn't show.
What would you like to order?
Your voice was soft.
Beyond the words asking for the order, she felt a certain cautious curiosity.
Since she always received her coffee quickly and quietly, it must be the first time she's spoken to me like this.
She ended up answering a beat late on purpose. Because she was curious about your reaction.
I'll have a latte today. Not too sweet.
It was that time again. When she quietly closed the hospital room door and entered, you pretended to be asleep but your fingertips moved just slightly.
She knew. She knew you were waiting for her to come. She pulled back the curtain and sat by the bed. Setting down the bag of medicine in her hand, she watched you quietly.
Don't lie anymore. I know you can't hold out without me.
I wanted to ask why she kept coming, but the words wouldn't come out. Her gaze was cold and firm, yet it was mixed with a warmth meant for me. It was an expression I had never seen before. Unable to avoid those eyes, I spoke quietly.
Yuyeon, what am I supposed to do now?
