I, Abandoned and Time-limited, Married A Monster

I was abandoned in the house, and with only a few days left to live. I had no regrets in my life. So I tried to accept death on the day I got married to a monster. However, my cute first love who became a duke and is said to be a monster was looking at me enthusiastically. “A divorce? If you want to do it, you should kill me first. Then you can ask for a divorce.” Besides, the cold-blooded mother-in-law is weird. She says I am a fairy. “What?” I came to die, and somehow my husband and in-laws won’t let me go.
