Sposa Scambiata, Viziata dal Boss

In my past life, I was forced to marry a cruel heir and was stabbed by my sister at my award ceremony. Reborn on contract day, I let her steal him. This time I just want to work, pay debts, and save Grandpa. But my new boss is the man I beat up in an elevator on my first day. Can the woman who died for love ever survive a second chance at power?
