Invited to Seunghyun's birthday party by Galchi, Gichun meets Seunghyun for the first time and cannot hide his joy. Seunghyun ignores Gichun, the middle-aged uninvited guest, but Sungjun, who was with him, falls in love at first sight. Galchi uses Gichun to gain favor with Seunghyun, and when Gichun finds out, he experiences jealousy he's never felt before. A party of gays whose gazes cross, no one knows how it will end.
