Pope-mobile

Hey all! I'm craving a super specific thing right now and I was going someone could point me in the right direction. Looking for an anime that has 1. Romance - specifically with like an over protective male. Extra points if he had some sort of dark mysterious past and or is like a vampire printer lol 2. Some action I watched vampire Knight but I never felt like I got any closure, so like a real ending would be nice too Thanks!
