It has been three days since my reincarnation in this world. Right now I'm being glared at by a handsome boy around 5 years old. Since i was born he comes to my room but he doesnt enter it.He stands near the door hiding and glares at me.What is his problem?

Wait...isnt he the brother of the villainess?.

In the story he was a cold character...only after meeting the heroine he opens up his heart and only treats her warmly.He hates the villainess since he thinks his parents dote on her more than him.Well the reason is our father treats him a little coldly since he is a boy and he will be the next duke.He wants him to grow up strong.But the duke smiles while seeing his baby sister.

He thinks she is just a good for nothing baby.She cant fight with swords nor she studies like him.She just sucks her fingers all day...

"...Wait,Did he just say that?!??How rude. I'm just a baby now.You just wait till I grow up"

And thats how he began to hate her more and more....

But that needs to be stopped.I dont want to die because of a child being jealous of his own sister.

First of all I need father to stop being cold with him.And then I need him to start loving me and caring for me as his sister.

But right now... I'm just a small child.What can I do?

But wait since I'm a baby its easier isn't it? *smirks*. Dont underestimate the charms of baby belle.

So I called out to him 'moooronnbrawtherrrrrcomeeehereee' Yup I said that but he doesnt get it...lol

My brother looked around for a bit.Since he saw nobody was near he came closer to me. He stared at me for sometime. I gave him the brightest smile a baby could offer. Wait is he perhaps blushing? How cute.

Then he regained his composure and scoffed at me. Then he suddenly reached out his hands towards me...hmm does he want to strangle me or something?He has this killing aura idk how to explain. You guys get me right?

I need to protect myself.....As soon as his hands reached my neck I grabbed one of his fingers with my little hands and smiled at him. He has become frozen at his spot.*chuckle* When I made that sound he then became uneasy.His face was red...My brother is such a tsundere.

He ran away from my room.
