Yu Ni 99 Tian

Fu Yan Ting was rescued in the deep mountains by a beautiful doctor and vows to find her. While hiding at his own wedding, he discovers that she is the bride his grandfather has arranged for him. However, she denies the connection and is insistent on maintaining the expiration date of their relationship—ninety-nine days. Song Zhi Luo hides her identity and resists his advances, but Yan Ting is nothing if not stubborn and resourceful.
