Kate’s ex-boyfriend Stewartaccidentally discovered a crack in the time tunnel and broke into New York in the 19th century. He used a miniature camera to photograph the New York Bridge construction ceremony and was discovered by Leo. Stewart wanted to avoid trouble. Escape the scene. At the banquet, Stewart was spotted by Leo while Leo didn't pay attention to sketching the elevator designed by Leo. Stewart fled to the New York Bridge to return to the present through the cracks in time and space. Leo thought Stewart was in danger to save him and was taken to New York City in the 21st century. After a series of encounters, Leo broke into Kate’s world. Two men and women who shouldn’t meet each other met. From the strange disgust at the beginning to the final love, they passed when Stewart was hospitalized because of an elevator failure. It had been a fulfilling and interesting week, although Kate still didn't believe that he was from the past. But the reality is cruel.
