Pregnant & Betrayed, I Married a Billionaire

Nora Foster grew up without parents and wants a family that is hers. She marries Ryan Miller and takes on his household with him, looking after his widowed sister-in-law Grace Lane and Grace's son Alex Miller. She gets pregnant and keeps delivering food orders through the pregnancy to keep the household afloat, and she takes all of it as building toward a happy life. Then, out on a delivery in the rain, she catches Ryan kissing another woman, and all the effort she has put in turns out to be a joke. Charles Foster turns up when she has nowhere left to go. He helps her get out of the marriage and stand on her own feet. Her child needs a household registration in the Capital City, and to get it she agrees to a contract marriage with Charles. After that she learns he has been in love with her for years, and as they live together she starts to warm to him. Then Charles's eldest sister-in-law comes home without warning, and Nora braces for the same thing to happen to her again. The sister-in-law treats her like a queen, the rest of the Foster family takes her in the same way, and the hurt she has been carrying starts to ease.
