Your Majesty

In this story Cross and Ink are brothers and princes
the kingdom was happy everything was fine so what could go wrong ?

Well...

Ever since the brothers were young their parents were very cold and strict, they planned on making Ink the next ruler of the kingdom because as they claimed he was "more serious, logical"
But the real reason behind their choice was he was very easy to manipulate due to past experiences.

cross on the other side was mostly neglected by their parents since they focused on his brother but he never really cared.

Although when he heard a conversation between their parents about their "project"...

He couldn't accept it.

He would not let this happen.

The same night, he sneaked in his brother's room and did what needed to be done.
