Substitute

My charming eldest brother.

My wise brother.

My fortunate sibling.

Most importantly, he is our parents' favorite.

What exactly am I? Of course, I'm always a secondary priority.

Because of our family's wealth and reputation, my grandfather and an old friend agreed to consummate the marriage between my older brother and the de la Vega's sole granddaughter.

It was originally intended for my mother and the de la Vega's son to marry, but when it was found that my father had gotten my mother impregnated, the two sides did nothing, and my father, of course, refused to agree that he would not be held responsible for what he had done.

As a result, our grandfather and his old buddy made another agreement: his eldest grandson would marry the de la Vega's eldest granddaughter once they reached the age of twenty.

Once again, it's all about money and status.

Because both parties are prideful, neither of them reneged on the deal. Isn't it been a long time? Can't they all just go on with their lives?

We are in the twenty-first century they should have considered the humiliation that may befall my older brother and that unlucky granddaughter of the de la Vega's.

Also, my brother has a girlfriend, and I know he has no intention of ending their relationship just because of that silly contractual marriage.

Anyway, this is my story on how I become a substitute for my brother.
