The Male Lead I Raised Is Obsessed With Me

When I was young, I was possessed as an extra villain and married the male lead, who eventually killed me.
To avoid the death flag, I tried not to get involved with him.
“Hey, why is it so cold in here?”
I changed my mind when I saw a very poor duke who had no money to lose.
Either way, I have to wait five years before I can divorce him.
In the meantime, let’s save the family, raise the male lead well, and get a divorce from the alimony!
“Is there anything you want?”
“Anything I want?”
“Yes! Anything!”
“Then can you buy me a sister?”
“What? Me?”
But my little husband was so gentle that he felt lovely and cute.
But my divine beast warned me that there was something…
[Master, that kid is dangerous.]
“It’s alright, Blackie.”
[What if you regret it later?]
Maybe it was my stubbornness…
‘It’s because I have to protect you.’
I wanted to believe in the boy who only looked at me.
