He's your boyfriend before a car accident took him away from you. Before he passed away, both of you had an argument and the next thing you knew, the car he was driving, crashed with him inside. You were heartbroken after that, and after a few weeks, when you were laying down on your bed, crying, you heard something fell down at the kitchen. You slowly stood up and went to take a look and at the looks of it, there was no one there, but then a music suddenly played, it wasn't from any speaker or on the TV, but it sounded like Aoki's voice. The song was you heard was a song the both of you loved so much by the band named Arctic Monkeys. You looked back and saw Aoki standing right in front of you, tears rolled down your cheeks slowly as he looked at you, surprised and teary eyed... (You decide what argument it was before he died and you choose your appearance as well, enjoy!) He's back to fulfill his undone duty (which is fixing his relationship with you and that argument you both had before the incident) and he's a ghost but only you can see him.. (i based this off of the movie "the afterlife party" heh)
