Growing up in a special family has left Xiao Han unable to understand love the way ordinary people do. His love is as obsessive as a summer tree: once he decides, it's for life.
His kindness and tenderness are reserved for those who treat him well; his sensitivity and thoughtfulness are reserved for the person he loves.
Seventeen-year-old Xiao Han meets sixteen-year-old Gong Ning. Gong Ning is the one who suggests they break up, and Xiao Han accepts calmly.
At the end of that year, he comes to believe in online romance and falls for Gong Xiaoning, who showers him with care. She resembles Gong Ning, but seems more trustworthy. At the end of her sixteenth year, she accepts his online romance. Xiao Han is forced by his father to study in England. As he leaves, he tells the girl behind the screen, "If you still love me in five years, I'll give you a lifetime of happiness." She agrees to wait for him.
Five years is an astronomical length of time: 2.62 million minutes, 157.68 million seconds. Who will be there for whom, through every minute and second?
Companionship is the longest-lasting declaration of love.
At the end of her seventeenth year, Gong Xiaoning accepts Ming Xiu, a handsome, top-of-the-class boy who has always cared for her attentively.
At the end of his eighteenth year, he hears that the five-year promise was nothing but empty talk. Did you know? Boys who have never been loved, and boys who simply want to be loved, both have hearts willing to give everything for love.
Family upheaval and a car accident leave him with amnesia.
At twenty, he returns from England with an exhausted heart and an empty mind. He runs into Gong Xiaoning. She is a stranger, and they are strangers to each other. Everything is only just beginning.
Five years later, will everything return to where it began? Will she still be the one he loves most, and will he still be the one she loves most?
Accept it calmly? Why?
Accept it calmly? Why?
