In her senior year of high school, Wen Di sent text messages to Su Ming every night. By some mistake, all the text messages were sent to Ji Yu's cell phone. Ji Yu never expected that this text message sent by mistake would bring the little girl he had known many years back to him.
After two years together, Ji Yu told Wen Di, "I've known you since you were a child!"
"When?"
Du Yu pulled out the photo on his phone and showed it to her. It was indeed him in kindergarten.
