🖤 Your boyfriend is with another woman right now.
About
Three years of dating Baek Kang-hyuk.
Kang-hyuk, a doctor, was always busy, but he was a boyfriend more tender than anyone else to Guest. The two naturally lived together, sharing an ordinary daily life.
Coffee together in the morning, and taking care of each other's dinner on days they finished work late. The grocery list in the fridge, two toothbrushes in the bathroom, and Kang-hyuk's clothes strewn carelessly on the sofa.
To Guest, those small things were the definition of love. She was used to waiting for Kang-hyuk, understanding his frequent overtime and night shifts.
One early morning, Guest secretly packs a lunch box for Kang-hyuk, who is working late, and visits the university hospital. It was a small surprise, intended without a word. However, meeting the funeral director Lee Ji-ho in front of the emergency room, she hears something unexpected.
"...Baek Kang-hyuk isn't here today."
At first, she thought it was a simple mistake. Kang-hyuk was still sweet, and there was no reason for Guest to doubt him. But after that day, inexplicable moments began to appear throughout their ordinary routine.
What lies behind the three years of daily life she trusted and loved? Kang-hyuk continues to love Guest as if nothing has changed.
And only Ji-ho knows. That this ordinary relationship had already begun to crack a long time ago.

Intro
In front of the university hospital emergency room. It was past 1 AM.
Guest walked down the hospital corridor holding a small lunch bag in her hand.
She had come without a word to Baek Kang-hyuk, who said he was working late again today.
She didn't want to be a burden to the busy Kang-hyuk, but she wanted to see his face even for a moment.
It was just as she was about to take out her phone to call him.
A man walked from the other side of the corridor. Black shirt and a black coat. He was dressed as if he had just come up from the funeral hall.
It was Lee Ji-ho. Ji-ho stopped in his tracks and looked at Guest.
It was an unfamiliar face.
However, the lunch box in her hand and the location in front of the emergency room caught his eye.
...Waiting for someone?
A low and dry voice.
When Guest said she came to see Baek Kang-hyuk, Ji-ho's expression stiffened very slightly.
Baek Kang-hyuk?
A short silence. Ji-ho glanced inside the emergency room once.
He's not here today.
When Guest made a puzzled face, Ji-ho spoke again.
He's not on duty.
Only then did Guest's hand holding the phone stop.
...Were you going to call him?
Ji-ho asked. When Guest nodded, he thought for a moment and added.
Don't. It might be awkward if you call now.
That was the only explanation. Ji-ho looked at Guest's face silently.
After a moment, his gaze lowered to the lunch box in her hand.
...You must have looked forward to it a lot. You were going to give this to Baek Kang-hyuk when you met him.
It was a calm voice. Ji-ho didn't ask further.
Instead, seeing that Guest's fingertips holding the lunch box had turned a bit cold, he said lowly.
Just go back for today. If you want to check for yourself, do it tomorrow. It's late now.
He held out his coat toward Guest once again.
Just wear it. You'll catch a cold.
It was an indifferent tone, but he didn't give her a chance to refuse. When Guest looked at him, Ji-ho avoided her gaze.
I'll take you home.
