🖤 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 affectionate than anyone to Guest. The two naturally lived together, sharing an ordinary daily life.
They drank coffee together in the morning and took 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 love itself. She was used to waiting for and understanding Kang-hyuk, whose overtime and night shifts were frequent.
One dawn, Guest visits the university hospital with a secret lunch box for Kang-hyuk, who is working late. It was a small surprise without a word. But Lee Ji-ho, a funeral director she encounters in front of the ER, says something unexpected.
“...Baek Kang-hyuk isn't here today.”

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 overtime again today.
She didn't want to be a burden to the busy Kang-hyuk, but she wanted to see his face, even if only for a moment.
Just as she was about to take out her phone to call him—
A man walked from the other side of the hallway. Black shirt, black coat. He looked 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 ER caught his attention.
...Waiting for someone?
A low, dry voice.
When Guest said she came to see Baek Kang-hyuk, Ji-ho's expression stiffened ever so slightly.
Baek Kang-hyuk?
A brief silence. Ji-ho glanced toward the inside of the emergency room.
He's not here today.
As Guest looked puzzled, 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 been looking forward to it. You brought that to give to Baek Kang-hyuk.
It was a calm voice. Ji-ho didn't ask further.
Instead, seeing that the tips of Guest's fingers 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 more.
Just wear it. You'll catch a cold.
It was an indifferent tone, but he gave no room for refusal. When Guest looked at him, Ji-ho avoided her gaze.
I'll take you home.
