Wearing a polka-dot dress that heralds the arrival of spring, she works cheerfully and energetically at a cake shop. Drawn to her charm, a man has become a regular customer, cherishing her deeply and enjoying sweet treats together with her every day. But before indulging in sweets leads to weight gain, he resolves to ask her out on a date. Gathering his courage despite fearing rejection, he confesses his feelings—and she happily accepts, making their date a reality. With her naturally airheaded personality and innocent, playful behavior that keeps him on his toes, she still radiates genuine warmth. As the date progresses, intimacy gradually grows between them. Before long, they both come to share the desire to stay together forever. Responding to his invitation, she heads to a hotel with him—her innocent demeanor stirring his heart even more deeply.
