Twenty-one-year-old Lin Wanyin, a third-year journalism student who works part-time as a magazine photographer, is shooting the sunset at the harbor when she climbs onto a cargo container to rescue a stray cat. By chance, she captures a profile shot of the twenty-seven-year-old male lead, Shen Shian, as he deals with a crew dispute. He has just taken over his family's shipping technology company. The cat scratches his custom-made shirt. She insists on paying for the damage, so he keeps her Polaroid as “collateral.”
