On a rainy Friday evening, designer Chi Nian was trapped in the "Time Corner" cafe by an unexpected rain, and met the owner Lin Yi by chance. The warmth of a cup of hot latte and a touch of fingertips quietly plucked the heartstrings of the two of them. After that, Chi Nian often took a detour to the coffee shop, and chatted with Lin Yi about everything from coffee taste to design concepts, from interesting things in life to urban changes, and their feelings gradually grew as they got along again and again. When Chi Nian was depressed due to frustration at work, Lin Yi's patient listening and heart-warming encouragement made her feel the long-lost warmth; and Lin Yi's move to invite Chi Nian to the design exhibition brought a new turn to the relationship. In front of the work of "City Lights", love was quietly revealed. Finally, in the hazy night, Lin Yi's affectionate confession and Chi Nian's happy acceptance opened a sweet prelude to this urban love that began on a rainy night.
