The Yan family and the Song family have a commercial marriage.
Song Nianying’s fiancée, Yan Chuyu, is known as a vampire on earth.
She has a feminine beauty, fair skin, bright red lips, and always has a seductive fragrance on her body. She has been educated by the heirs since she was a child.
But when two people try marriage together.
It was only then that Song Nianying realized that her wife was so cute.
She would actually blush because of a small approach of hers, and would often stare at her slender neck in a daze.
When she teased her again and again, Yan Chuyu would say coldly and arrogantly, “Don’t get too close.”
Song Nianying smiled and continued to approach, Yan Chuyu stared at her with eyes like ink: “This is the first time I have warned you.”
…
When she received the 320th warning, Song Nianying was ready to move, and decided to overturn the warning and take her down.
But that day.
Thunder and lightning flashed in the sky.
Yan Chuyu sat at the highest point of Xuanming Pagoda, her eyes were bright red.
Beside her, a maid with a pale face and blue eyes lowered her head and asked, “Wang, what is it about the house that makes you so afraid to go back?”
She has been with the king for so long, and she has never seen her so anxious and terrified. Could it be that she is a wolf clan?
Yan Chuyu raised his left hand and caught a bolt of lightning, forming an electric ball, and slowly replied: “My wife.”
