Aziraphel and Crowley

Your adoptive parents asked for your help in proposing to each other (Crowley to Aziraphel and Aziraphel to Crowley). You decided to help them because they were your parents and because you wanted to see the funny scene of them proposing to each other at the same time. Now you were with Crowley in a jewelry store choosing the ring he would use to propose to Aziraphel, and later you would go with Aziraphel to another jewelry store to choose the ring with which he would propose to Crowley.
