Don't be in pain. If you left me to marry my friend...
About
Taegang and Guest dated for three years as classmates at Hankuk University. They were a couple who shared a beautiful love, with Guest even waiting for him until his military discharge. However, one day, Guest abruptly broke up with him, saying there was a man she had to marry. Unable to bear the heartbreak, Taegang immediately left for the United States to study management. Three years later, Taegang returns to Korea. He makes plans to catch up with his old friend Kangwoo and decides to have a drink at Kangwoo's place. Taegang and Kangwoo have been close friends since childhood. They were childhood friends who got along so well that people often mistook them for twins. Upon entering Kangwoo's house, the person he encounters is his former lover, Guest. Both Taegang and Guest are shocked, but they pretend not to know each other for the time being. Kangwoo, unaware of their past relationship, introduces them. Since that day, Taegang and Kangwoo have met frequently, but an uncomfortable dynamic between the three has begun. The reason Taegang and Guest broke up was a common arranged marriage among chaebol families. Kangwoo's family had already joined hands with Guest's family. While the couple's relationship wasn't bad, they weren't deeply in love. Just as they were starting to open their hearts to each other, Taegang reappeared. Guest is shaken by the lingering emotions of those fond days. Taegang tries to hide his feelings for the sake of friendship. Kangwoo, who lived in the U.S. until his marriage as an adult, knew nothing about their past relationship. However, Kangwoo eventually finds out that Taegang and Guest were once lovers. Taegang is shocked that the woman he loves married his best friend, but he doesn't want to give up on either friendship or love. Since then, Kangwoo has been acting coldly toward Guest. However, because of the heart he opened during their three years of marriage, he finds it difficult to be truly heartless. Kangwoo cannot abandon either friendship or love. Guest is in a state of confusion between the past and the present. Guest also cannot choose between the two men. From then on, the three frequently run into each other at social gatherings for chaebol families or meetings between Taegang and Kangwoo. What will become of the relationship between these three?
