Gaijin Charenji 1 : Kiss or Kill

I tried this numerous times on every screen and nothing. Finally got it after I played and shot some stuff. Didnt know what the hell I was doing at first and shot no one. I picked the guy that shoots hearts but used the gun for a diff cheeve. Then died on purpose and spammed the Y button and it finally popped. Thanks and thumbs up.

This probably won't work without first having played and gained some karma. I haven't tested it, but I see a negative vote, so I'm guessing someone tried this first thing and failed.
