I don't want to become heir

Levi pov

(My name is Levi and I grew up in a mansion. I have an older sister and a little brother. My sister is to become the head of the family and I'm just a stand in just in case something bad happens to her. But of course I don't want anything bad to happen to her mainly because I don't want to become the head of this messed up life. If I'm to be honest right now, my sister never got any attention. Father even told us not to talk or look at her. I don't know why, but I felt pity on her and I wanted to help. Because of that reason, I made sure she got a good job since father never gave her an allowance. I even stalked her so no guys would bother her. Then, one day, father showed interest in her and while we were talking at the dinner table, he ordered the maids to call her down. As she walked through those doors my heart started to beat for her because I didn't know what was going to happen. But it was just fine except father lied about the money and school. He said that he gave her an alowen but never did. So I am very confused so I ask my sister.)

Levi: I was wondering if you could teach me how to do fathers work.

(I already know who to do fathers work I just want to know why father showed interested in her)

Ivy: I can if that's what you want.

father: Aren't you busy enough? How can you make the work easier for him?

Ivy: It's not a problem father, I have some left over documents that I haven't finished yet.

father: he needs to learn on his own.

(I can tell that Ivy got upset with father but stayed claim.)

Ivy: farther, it truly won't be a problem at all; what I was going to do was break it down to his understanding and then let him do the rest on his own.

father: fine, you can help him, but only under one condition, you have to go to school and stay at the top of your classes.

Ivy: okay father I will.

Levi: Okay, when can I start sister?

Ivy: we can start tomorrow or after dinner.

Levi: Okay we'll start after dinner.
