One night stand

Interior designer Ji-yeon first meets Jun-seok when her car breaks down and he gives her a ride on his motorbike. They meet again later that night, at her future father-in-law's birthday party, when it turns out that Jun-seok is one of the waiters at the event. When her fiance couldn't come to the party because of his work, Ji-yeon gets upset and has a drink by himself at the pool after the party. Jun-seok joins her in drinking and tries to kiss her. She slaps him and resists him at first, but she eventually gives in and has a one night stand with him beside the pool. After that night, Ji-yeon regrets it and she doesn't want anything to do with Jun-seok anymore. However, he cannot accept it and begins terrorizing her.
