A photo made Nan Bei remember him. Years later, he joked that he didn't ask for his contact information at that time. He really regretted it.
When they met again, the man in the photo stood in front of her and said with a smile, "You seem to have grown up."
In front of the floor-to-ceiling windows, two young and tall figures stood one behind the other, and the warm sunshine hit them both.
"Why did you laugh at me when I first met you?"
"It's not east and west, it's north and south."
"... You are nothing."
I met you on the journey, and the chance encounter lasted the rest of my life.
