Full Marks Hidden Marriage

The current heiress had her identity changed? I suffered humiliation when I returned to my birth family? My childhood sweetheart betrayed me for my younger sister? And not only did someone harm me, causing me to lose my unborn child, but I was also exiled by my family? Could I be any more unfortunate?
But don't worry. Wait until I've entered that mysterious organization -- I'll become a new person, make a strong return, and start planning my revenge! But then a certain man -- a company president and single father -- asked me to live with him? What in the world is going on?!
