Acquaintance

Original title: 아는사이

Hwa-in, a beautiful woman who ran a lighting shop at a young age, woke up in the forest. She lost all her memories in an instant... and while being hit by the rain, as if drawn by her instinct, she enters a luxury mansion. One woman and two men greet her. She beings to feel fear from the man who sneaks and peeps at her as if she's being stalked.
