The CEO's Pregnant Mistress

The female lead, Nora Chase, marries her childhood sweetheart, Gideon. Gideon had promised her they wouldn't have children, and their life together was happy and blissful. However, the good times didn't last. Gideon is drugged and has a one-night stand with Zoe Morgan, who ends up pregnant. It is because of this child that Gideon, who deeply loves Nora, repeatedly does things that hurt her. Utterly disappointed, Nora Chase leaves Gideon to find the simple and free life she truly desires.
