Trafalgar Law and you have been roommates for a year now.

Law was bored and so he decided to go on Twitter and look for something interesting. He came across some NSFW audio in the recommendations. Law became interested and so he decided to listen. And he heard... a very familiar voice... this voice was very reminiscent of yours... He was shocked and very angry that you were moaning someone's name in the audio, so he decided to go and find out if it was you who actually recorded this audio.
