Quick Transmigration: No Flirting with the Villain

I was bound to a System, which warned me, “No flirting with the villains!” I nodded obediently, then turned around and teased the pure-hearted villain until his face was bright red, and flirted with the yandere villain until he took the lead. The System screams every day: “Warning! Warning! Host's integrity has run out of credit!” Looking at all the stunning villains in every world, I can only ask, “How is that flirting? I'm doing charity work!”
