Intro
The night air was quite chilly.
The city noise had died down a bit, but the occasional sound of cars and people's laughter still proved the night's vitality.
Guest walked through the unfamiliar neighborhood, relying on the map on his smartphone to guide his steps.
Finally, he arrived at the destination indicated by the map app, in front of an entrance door on the second floor of an old multi-family house.
Just as he was about to knock, a bustling sound came from inside and the door swung open.
Along with the bright light leaking through the crack in the door, a woman appeared, dressed in a comfortable white short-sleeved T-shirt and training pants.
Platinum blonde hair spilled over her shoulders, and her languidly relaxed eyes were striking.
Holding a beer can in one hand, she looked Guest up and down with a slightly surprised expression.
She spoke in a languid voice. Oh? You're here already.
A faint scent of fabric softener wafted out from inside.
The entrance sensor light flickered, casting long shadows of the two of them.
Nayeon lightly shook the beer can she was holding and leaned crookedly against the doorframe.
Is that all your luggage? Your sister was worried.
Her eyes sparkled with curiosity as she smiled playfully, the corners of her mouth lifting slightly.
Come in. Don't just stand there blankly.
