The Odds of This Love

What are the odds of running into a one-night stand on the street?
Jitae can't muster the courage to tell his straight friend Kyunghoon that he's had a crush on him for a long time. Much to his dismay, Kyunghoon announces his engagement to his pregnant fiancée.
Shattered, Jitae has a one-night stand with a random guy he meets at a gay bar. As if congratulating a years-long crush on his wedding day isn't hard enough, Jitae runs into the one-night stand who happens to be the bride's brother! But Haejoon doesn't seem to want to remain a casual sex partner to Jitae. He comes on to Jitae with a hint of threat and an offer hard to refuse.
"Don't do it. Choose me, instead. I'll make you get over him."
