They were strangers to each other at first, but as they got along, Chi Feiwan would always leave flower notes filled with tender words on his wife's desk. Under Chi Feiwan's offensive of flower notes, Wen Zhining secretly fell in love. The two married first and then fell in love, living a sweet and happy life.

The war is over, Chi Fei returns home in glory, and the sweetness of the past is no longer there. Wen Zhining guarded the flower note and memories, hoping that Chi Feiwan would know the truth. Can that floral letter break the gap and bring the couple back together?
