Synopsis:

I transmigrated into a novel that I read years ago as the second Prince of the Chrono Empire and was fated to be killed by my half-brother, the First Prince at the age of 12.

So, What's my role in this novel?

Am I the villain?

Am I an insignificant extra?

Am I the protagonist? Nah, definitely not.

But, why bother?

Following the novel's plot isn't my style and I won't let it dictates my life.

Regardless of my role, I am the main character of my own life.
