Did you never have a crush?

"Seriously. Did you never have a crush, Onii-chan?"
"Of course I didn't. You know that I never had the time for that"
"But Onii-chan... I remember you once introducing me to a girl. I just can't put a face to it."
"I don't recall that."

Killua is confused. Ever since he had a discussion with Alluka he starts getting weird dreams and flashbacks, he doesn't recall, specifically a girl he thinks to once have known. Just who haunted his once peaceful mind? Just what was this feeling that lingered deep in his heart? Just how did he forget?
