Of course, the following is a touch-up version of the original copy.I enhanced the emotional level and carefully portrayed the characters' psychology and the atmosphere of the times, making the story more infectious and picturesque: --- Yeon-du is about to go to the United States due to heart surgery. Before leaving, she entrusted the deepest secret in her heart to her best friend, Bora.She begs Bora to quietly investigate the man named Baek Hyun-jin, a name she couldn't easily say. To fulfill the wish of his friend, Bora decided to start with Baek Hyun-jin's closest person—his closest friend, Pung Woon-ho.However, her plan was clumsy and reckless. She had originally planned to approach quietly, but she unknowingly deviated from the track and headed towards a direction that she had not expected. Back in 1999, on the eve of the coming of the new millennium, seventeen-year-old Bora was standing in the center of her youth.At that time, she also fell into the hot vortex called "first love" for the first time with the unique stubbornness and shyness of a girl.It was a heart-warming without warning, and it was also a gentle secret hidden in the folds of time. --- If you want to add more character details, era background or specific emotional styles (such as sadness, sweetness, suspense, etc.), I can continue to optimize and adjust.
