It is now 9 o'clock in the evening. In the Beihai Apartment in City A, every house is brightly lit, especially in Building 6, which has the highest lighting rate - no lights are turned off.
And through each window, there is the noise of a family of three happily watching TV, the noise of couples quarreling and fighting, and the laughter of migrant workers crowded into two-bedroom apartments, smiling and discussing their daily experiences... There is undeniable that there is a story in every window, whether sad or sad, bitter or sweet...
But today is very special for the owner on the 7th floor of Building 6, Mo Xiaoai, because today is her 25th birthday.
25 Years old is nothing to a girl who comes to city A to work. She has passed the age of acting coquettishly in front of her boyfriend, and has also passed the age of being distressed for a long time by her boss's words. But today she is looking forward to it because she received a letter - a letter from her boyfriend from France, and she plans to open it later.
So, in this building window, our story begins!
