The number one assassin of an assassin group and the empire's best general both fell down a cliff while they were fighting with each other. After falling down this cliff, their lives would never be the same again.

The assassin woke up inside of a kind hearted girl's hut, while the general was rescued by an assassin group and was brought to their base in a cave below the cliff.

As time goes by, would the assassin slowly become a kind hearted person like the girl while the general slowly adapt to the life of an assassin and become a traitor to the empire that he serves.
