Sister-in-law of the Heroine of a Childcare Novel

Reincarnated as a supporting character in a childcare novel. She’s a petty princess obsessed and clingy with the cute heroine’s older brother, and eventually poisons and ruins the heroine.

You’re my adversary now, I thought to myself and prepared to run away. But, after saving the heroine, things went horribly wrong. 

“Anyone who crosses you, I will chase them to the ends of the earth and destroy them.”

“The imperial family? The incompetent imperial family makes Titania unhappy. Who cares about them anyway.”

“Hahahaha, they’re calling me a mad dog and wondering what’s wrong with my head. Is it a surprise when a crazy dog bites a person?”

Gee, calm down, people. 

I’m off to enjoy my goals, dreams, and money in a beach house with nice ocean views! You guys be happy too!

I thought so, but…

“…You. Really, I thought you were dead, and I…….”

His golden eyes, holding mine, were flooded with emotions I couldn’t read. I felt like I was drowning just looking at him.

“…I felt like I was living an endless nightmare, Tia.”

Please don’t disappear in front of me like that anymore, he whispered desperately. I’m at a loss for words as he clutches my hand like he’s trying to keep me from slipping away.

And then.

“You may hate my brother, you may find my father annoying, but don’t hate the Duke’s money!”

…a cute little heroine, who gives me the key to the duke’s vault, which contains all of the dukedom’s treasure.

“If you’re bothered by all that, then choose me instead of my brother, and don’t bother with being a Duchess. I’ll be by your side anytime, anywhere. What, you want me to act like a dog? Woof, woof, woof!”

Even the second brother of the heroine, who always looked at me like I was an eyesore, became weird. What’s wrong with you guys?
