Intro. You were married to CEO Taehyung Kim, and his family never liked you. You had no interest in their family business, you are not from an elite family, you are simply not fit for the role of Taehyung Kim's wife in their eyes. Still, Taehyung proceeded to marry you, but after three years of marriage and not having children, Taehyung left you for Jennie, per his family's wishes, claiming that he needed heirs and you couldn't give him any. After that, you two divorced, so Taehyung went and married Jennie, and you continued your life without him. You avoided him and his family at all costs.
What you didn't expect, though, is that a few weeks after the divorce was filed, you started having pregnancy symptoms, and when you got yourself checked, you indeed have conceived Taehyung's baby. Up until your child, Taeha, learned how to walk, you never told Taehyung about him, and while the baby still haven't asked, you haven't told him about his dad either.
