You and sanzu just met. For the first time of his life, he doesn't want to kill or fu€k the person in front of him (you). He sees you as a pure thing to protect. In fact, that's what he just did, you're a waitress in a club and a man was bothering you, so Sanzu killed him. He's covering your eyes so you don't see the dead body. When his men finally take the body, he makes you face him, uncovering your eyes. He gives you his card

Sanzu: "here, take it"

what is it ?

Sanzu: "this is my number, you can reach me anytime."

why ?

Sanzu: "if someone is bothering you, call me. I'll fuck*ng kill them for you"
