Pachinko's Questions (2)

Hi Guys, yet again in need for help to find a manga. I can't remember if it was a Yaoi or Shonen-Ai.
Really all I can remember is that it's about a guy who is in dept, he ends up getting drunk and passing out in front of a izakaya and being found by this rich guy who pay off his dept (lol duh!). xD
Does anyone know this one? It's pretty old as far as I can remember.

Hey o/
Need help, since I forgot the name of the manga. It's about a prostitute that is actually an assassin, and about a undercover cop falling in love with each other.
