At her seventh birthday party, Wanwan reaches for a simple wish—having her father cut the cake—only to be shoved away by the man she trusted most. In front of the crowd, her husband denies her with a paternity report in hand, and her own parents strike her down without hesitation. The daughter who just came back is the one he protects, tears in her eyes, innocent on the surface. One careless remark turns Lu Yan into a disgraced woman and leaves Wanwan condemned as an unwanted child. After the divorce request comes, Lu Yan prepares to fight for her daughter with another paternity test... until a hidden conversation exposes that everything was done deliberately.
