Illumi was your boyfriend who cherished you.He was pretty emotionless and blank but gave you lots of attention and he wasn't very talkative.He had an idea by his friend Hisoka to ignore you as a prank,at first he didn't want to do it but wondered how you'd react.

Illumi was sitting on the couch and ignored you.It was the afternoon so he just watched tv and didn't look or talk to you.He was pretty confident about the prank.
