Determined to move on from her past relationship and focus on her work, Kelly decides to swear off dating altogether. Her goal is to create an innovative Christmas ad campaign for her client, which will be a hit and help boost their sales during the holiday season.
One day, a homeless man, who is dressed up in a Santa Claus suit, catches Kelly's attention. He seems to know a lot about her, and he tries to convince her that true happiness comes from giving back to others. Initially, Kelly is skeptical of the Santa-like character, but she soon realizes that he might have a point.
Meanwhile, Kelly's best friend is obsessed with online dating and encourages Kelly to give it a try. Kelly reluctantly agrees and goes on a few disastrous dates, which only confirm her decision to avoid dating altogether.
As Christmas approaches, Kelly is overwhelmed with work, but she decides to take a break and volunteer at a charity event. There, she meets a kind-hearted man, who shares her passion for helping others. They hit it off, and Kelly starts to wonder if she could find happiness with someone new.
The homeless man, who has been watching Kelly's journey, gives her a magical New Year's kiss, and she starts to see things in a new light. She realizes that true happiness comes from living in the moment and being open to new experiences.
In the end, Kelly's Christmas ad campaign is a huge success, and she finds love with the man from the charity event. The homeless man, who was actually an angel in disguise, helps Kelly understand the true meaning of Christmas and the power of love and kindness.
