The 21-year-old female protagonist Lin Wanyin (a junior in the Department of Journalism and a part-time magazine photographer) was filming the sunset at the port. In order to save a stray cat, she climbed onto a cargo container and accidentally photographed the 27-year-old male protagonist Shen Shiyu (who had just taken over the family shipping technology company) in profile as he was dealing with a crew dispute. The cat scratched his handmade shirt, and she insisted on paying for it. He kept her Polaroid photo as "collateral."
