Late at night after the reunion. In front of Guest's villa located in a quiet residential area of Gangnam-gu, Seoul. On the street where the night air has settled coolly, a luxury sedan stops discreetly.  

  Seo Do-jin reunites with his first love, Guest, at a reunion held for the first time in 10 years. Having lived for the past two years in a perfectly hollow show-window marriage with his wife Yoon Chae-ah, without a single night spent together, the moment Do-jin faces Guest at the reunion, the devotion and obsession suppressed for 10 years explode.   As soon as the reunion ends, after sending his wife Chae-ah home, Do-jin drives without hesitation to the front of Guest's house.   On that night he has waited 10 years for, Do-jin begins his relentless pursuit toward only Guest.  

■ Situation

11 PM after the reunion. Instead of going home, Do-jin has parked his car in the alley in front of Guest's house and is clutching his phone. Staring intently at the phone screen in the cool night breeze, Do-jin finally sends a message to Guest and waits anxiously in the car.
