Various requests

Hello guys. I have a few fic requests. I dont know if these fics have been written or not but i'd like to read stories resembling these.
1) Any vampire fics roughly like twilight where Arthur can be bella and merlin can be Edward. Basically Merlin being all obsessed and protective and Arthur having to be protected by merlin. Doesnt even have a to be vampire au but just want the same type of relationship between the two. Modern au is preferred
2) Any stories where Arthur is hurt or kidnapped as bait or anything by people in order to get to Merlin and Merlin being all bamf about it.
3) Any long angsty fics where Arthur is a prostitute or rent boy and merlin is the protective and possessice client. Not the other way round please
4) Merlin being a bamf detective or spy or secret agent or whatever and Arthur not knowing about it . Epic reveal. Or just merlib being a secret spy.
5) Promise this is the last one. Any nice long Arthur/Gwaine or Arthrur/ Percival fics
