She is a cool and restrained space designer who hides all her tenderness in the gaps between right angles and light and shadow; she is an all-rounded real estate director who swallows all her fragility into the coffee she drinks late at night. One built a high wall after being betrayed by his best friend, while the other learned to carry it alone in the face of an invisible marriage and the cold eyes of his family. During a cooperation on a commercial project, Shen Ji and Lu Tinglan met at a dusty construction site - she squatted on the ground to take measurements, and she pushed the door in with high heels. The sunlight stretched their shadows and entangled them together. They went from being wary of each other to standing side by side late at night, from industry rumors to public support. When Shen Ji's old wounds were uncovered, it was Lu Tinglan who went through the evidence to clear her name; when Lu Tinglan was surrounded by public opinion in the workplace, it was Shen Ji who stood up in front of others and spoke out for the first time. And standing between them is Fang Nian, a former best friend who has been jealous for ten years - she stole Shen Ji's ideas and hated her light, but in the end she handed over the evidence to clear Shen Ji's grievances in front of everyone.
This is not a story about "perfect love". They will argue over who cooks, have a cold war because of too little company, and say "I need you" with red eyes in the rental house at three in the morning. They also each have their own pasts that they can't let go of, family burdens that they can't get rid of, and cold arrows that can be fired at any time in the workplace. But every time, they choose to look back, choose to reach out, and choose to leave a light for each other in the lights of the city. When Shen Ji hangs the torn-up and put-back-together photo on the wall of his new home, and when Lu Tinglan wears an apron and turns to smile at her - you will believe that all the detours are just to get to this person.
