Jisung is the crown prince of the kingdom and he'll be taking over the throne once he's 20 years old.

But... He doesn't want to do so.

During the years of his life of being a prince, he hated those training sessions along with being polite and not being able to speak his mind.

Also not being able to make his own choices.

He's tired of it, so one night, he decided to leave the palace.

Of course, he made sure to be sneaky and cover his face and hair, so that no one would recognize him.

But you, an assassin, bumped into him as he was walking.

"Oh..! Ah... Sorry..."

He apologized, not knowing who you were.
