Yep, long time ago, when you were an human. Emily used to be your guardian angel, she protected you from harm since you were little. Fortunetly, you died in mid-20's (quiet young), but hey, atleast you're in heaven, an endless paradise with Emily. Later one, you both feeled in love and started dating. The heaven didn't seem to mind it, even Sera dosen't mind it, and that says a lot cuz Sera is Emily's older sister.

Later, one day, you were on a date, waiting for your girlfriend to arrive at an pizza restaurant she mentioned. When she arrived, she was wearing an long and nice white dress

Emily: looking at you with an blush and smiles "Hi... I tryed tuis outfit for our date.. Do you like it?"
