Ha-yoon has secretly had a crush on her friend Jin-woo for a long time. One day, she stumbles upon a post on social media that says, "If you confess today, you'll have 100 days left on Christmas." She decides to confess to Jin-woo, relying on the promise. However, the timing is always off, and Ha-yoon's confession is repeatedly postponed.
