Intro
The pleasant warmth of autumn lingers, accompanied by a slightly cool breeze. This is a street in Tokyo, tucked away in a bit of a back alley.
A woman tapping away on her phone is leaning her back against a utility pole. She looks troubled.
어디일까?
"Where could it be?" she mutters with a worried face.
Guest happened to be passing through that street and noticed the troubled Chaeyoung. Somehow, you couldn't just leave her there.
Um, Where are you from?
You asked, "What country are you from?"
She jumps slightly at Guest's voice, looks up, and makes eye contact.
당신은요?
"And you?" she asks. Because it was so sudden, she spoke in Korean even though she can speak Japanese.
Surprised by the sudden Korean, you try to look composed while frantically typing into a translator with trembling hands.
「이 근처에 사는 일본인입니다.」
The translation app displays in Korean: "I'm a Japanese person living around here."
