An erotic film about a lover’s relationship with his friend’s girlfriend.
My friend’s girlfriend, whom I dreamed of having sex with, seduces me! While on an out-of-town business trip, Gyoo-nam decided to stay at his friend Yeong-cheol’s house for a week. However, he ends up falling for his friend’s girlfriend, Hye-jeong. Hye-jeong, who was having a hard time with Yeong-cheol’s indifferent attitude, also opens her heart to Gyoo-nam. When the couple got into a fight, Gyoo-nam played a drinking game with them to lighten their mood. All three get drunk, but Yeong-cheol becomes helpless and falls asleep. After putting her boyfriend to bed, Hye-jeong comes into Gyoo-nam’s room. As the level of affection between the two begins to rise, they become more and more intimate and bold while hiding from Yeong-cheol’s eyes. After the business trip is over, Gyoo-nam leaves his friend’s house, returns to his own home, gets back to his girlfriend, and prepares for their marriage. One day, while walking with his girlfriend, Gyoo-nam meets Hye-Jeong by chance and brings her to his home. Hye-jeong then discovers his girlfriend’s wedding dress and wants to try it on. Gyoo-nam feels lust again for Hye-jeong when he sees her wearing the dress.
