She Raised Her Ex-Boyfriend Niece Very Well

“Artea is my niece.”
“She’s also my niece.”
It is 100% correct to say that you should not have double in-laws. I was just trying to raise my niece.
“Bellona, Marry me.”“Artea is my niece.”

“What?”
“Isn’t this the best way for both of us to raise Artea?”
Suddenly, the contract marriage with my ex-boyfriend began. No way!
“My uncle loved my aunt so much that he asked her to marry him.”
“Aaaah, it’s romantic!”
But is it okay to lie to this extent? I did it?
“Wow, dancing with my aunt and uncle is pretty!”
“My aunt and uncle love each other so much, so they say I have to go out with them sometimes to go on dates!”
Thanks to my niece’s help, or rather, interference. Now I sleep in the same bed every day. Is this… right?
“Auntie can’t run away. If she does, my uncle will catch her.”
“Yes. I won’t let you go!”
It is clearly a contract marriage made with divorce in mind, but there is no way out.
