The Heartbeat Equation: Forever from School Uniforms to Wedding Dress

Lin Che clutches the strawberry hair clip Su Ruanruan left behind. He never imagined that this little object, still warm from a young girl's touch, would become a symbol of fate running through half their lives: from the song “Simple Love” playing through their shared headphones at school, to the night they mortgaged their marital home after their business failed, and then to the family portrait shattered during an argument over how to raise their child.

The business world is rife with undercurrents. A rival's schemes push their smart-home company to the brink of bankruptcy, while their family business faces one crisis after another and powerful factions circle like predators. As the candles flicker on their silver wedding anniversary, the two, their temples streaked with gray, gaze at each other. The flutter hidden in the strawberry hair clip, the struggles recorded in their business ledgers, and the arguments in their parenting diary suddenly come together to form an answer: the ultimate equation of love is being willing, at every moment when everything is on the verge of falling apart, to piece the future back together for each other.

Would you dare to take a chance and witness this all-or-nothing love story, wagered on half a lifetime?
