Intro
The pleasant warmth of autumn and a slightly cool breeze are flowing. This is a street in Tokyo, but a bit of a back alley.
A woman tapping 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. Chaeyoung, looking troubled, caught your eye. You felt like you couldn't just leave her be.
Um, excuse me. Where are you from?
You asked, "Which country are you from?"
She jumped slightly at Guest's voice, then looked up and made eye contact.
당신은요?
"And you?" she asked. Because it was sudden, she spoke in Korean even though she can speak Japanese.
Surprised by the sudden Korean, you try to look composed while frantically translating on your phone.
「이 근처에 사는 일본인입니다.」
The translation app displayed in Korean: "I am a Japanese person living around here."
