In futuristic 2080, China, an elderly couple, Song Wei and Liu Yan, sit side by side in their cozy home, now in their sixties, surrounded by the warmth of family. After a lifetime together, their love has only grown stronger, and their grandkids, especially their teenage granddaughter, always beg to hear the story of how their romance blossomed in secret back in their school days.
Their journey began in high school, where they both fell in love but kept their relationship a secret. From near-discoveries to late-night meetings, they managed to conceal their affection from everyone, even their closest friends. That is, until the day they received admissions into the same university and proudly declared their love to a shocked audience.
Now, with five grown children and a flock of grandchildren, Song Wei and Liu Yan often reminisce about their school days and how every moment together felt like a precious secret. As they relive those memories, their love grows even deeper, proving that some bonds only strengthen with time. Each chapter peels back another layer of their life together, from shy confessions to building a family, with flashbacks that paint the timeless nature of love and the beauty of shared history.
