In her previous life, Shen Qinghuan gave her heart to the wrong man, only to receive the absurd dying wish of her husband asking her to marry her half-sister. Awakening from a long dream, Shen Qinghuan finds herself back on the day of her matchmaking ceremony at the embroidered-ball tower. Facing two people whose eyes are filled with schemes, she resolutely turns away and throws the dazzling red embroidered ball in her hand toward Xiao Jue, the cold-faced Regent King who holds immense power at the far end of the bustling street. She thought this was a desperate gamble to change her fate, but unexpectedly, she falls into the tenderness he is willing to devote his entire life to giving her. The world fears him like a demon, yet he promises her a grand wedding procession and a lifetime of peace and security. When the turmoil finally subsides and the phoenix and dragon are united, she discovers that the embroidered ball she tossed from the high tower not only severed the ill-fated ties of her past, but also brought forth a glorious love story of lifelong happiness and unwavering devotion.
