I Am a Killer

To put it simply, my identity is that of a killer, and to be more specific, I am the apprentice of a top killer... But this does not prevent me from calling myself a master. But I, who is so gentle and sweet, have received such an incredible task - to protect the son of the boss who is unpredictable and changeable. No matter how clumsy my killing skills are, you can't let me do such an unskilled thing. God, what do you want me to do? ! This article is purely fictitious. If there is any similarity, beat him up for me.
