President Liu Yan misses the childhood marriage engagement. To confirm the true essence of this relationship's sincerity, he prepares generous gifts, hides his identity, puts on simple work clothes, and returns to his hometown to keep the ten-year appointment with Su Xiao. Facing family and friends' different considerations based on reality, other people's courtship and pursuits, and the ups and downs of the Su family's domestic affairs brought out by the old house demolition, Liu Yan calmly and gently responds, while also silently observing and caring. Su Xiao always firmly guards the feelings deep in her heart, resolutely standing by Liu Yan's side to face the twists and turns in life together. When his identity is revealed, the two see each other's sincerity clearly, and finally walk hand in hand into a fulfilling marriage.
