In the opening scene, we meet a woman named Wenda who is jogging with her friend Sun Hee. During their conversation, they talk about relationships, with Sun Hee suggesting dating multiple people. However, Diane disagrees as she is still emotionally attached to her ex-boyfriend Jonjin Sock. Diane works as a designer in a private company but is often disregarded by her superior. After confronting him, Diane quits her job and later gets a two-month contract at a company called Fly where her friends Yongji and Sun Hee also work, bringing joy to them all.
