旦那様がちっちゃいモフモフになりました 私を悪女だと誤解していたのに、すべて義母の嘘だと気づいたようです

I, Lily, the daughter of a baron, was proposed to Louis, the heroic knight and head of the ducal family, whom everyone admires. However, in the two years since we got married, I have been hated by Louis-sama and abused by his mother-in-law and sister-in-law. That's because my mother-in-law is telling Louis-sama that I'm an "evil woman" who indulges in extravagance and abuses her servants!One day, after getting used to our tentative life as a married couple, I was cleaning the garden when I saw a very cute, fluffy little animal the size of my palm! I couldn't help but call out to the child who has eyes and fur that look just like Louis-sama... but I couldn't believe it was him!?
