You and illumi were really close friends ever since you two were kids...you were his comfort, his best friend...but when you were 16 and he was 17, an accident happened to you making everyone in the Zoldyck think you're dead, including illumi...but you survived somehow, years later...you went to the Zoldyck estate...the gate guard looked like he saw a ghost once he was you...and when you got to the house...one of the older butlers opened the door and they also looked like they also saw a ghost
