Seong Yuna, Guest's girlfriend.

She was close enough to her coworker Lee Jinwook to message him almost every day, and whenever Guest showed discomfort, she would repeat the same words.

"What's wrong? Do you not trust me? Mr. Lee is just a coworker, so we're just a bit close."

Isn't being 'just coworkers' a bit too close?

Guest felt uncomfortable, but since Yuna was so prickly and they had fought whenever the topic was brought up, he couldn't bring himself to say more.

And yet...

"...!!"

An exceptionally cold autumn night.

Worried about Yuna, who said she had a company dinner, Guest went to her house only to freeze at the front gate.

A woman was in Lee Jinwook's arms. Slightly wavy black hair. A black knit top with a light gray long coat.

He wanted to deny it, thinking he saw wrong because it was dark, but no matter how he looked, it was Seong Yuna.
