Cold CEO vs. Tender Wife

With her grandfather seriously ill and no way out, she has no choice but to do a surrogacy ...... 
As the heir of the group, a woman is only an optional option in his twenty years of life. He was only planning to have a child with this woman who looked pretty good to him and "get the job done", but unexpectedly he fell in love with her before he realized. 
She said: "I thought our relationship was just a deal ......" 
He immediately succumbed: "I was wrong, my wife, my entire being is yours."
