help i forgot the name of an good korean/japanese serie. it was about a boy who likes a girl and she got abducted and everybody forgot about that girl, not the boyfriend. the story ends up with the boy playing deadly games in another dimmension (like group games) with a few friends (made at the game) and theres the psycho dude who is obsessed with killing people ingame and at the end theres the girl locked up in a game who no one ever could end. there were multipel dimmensions and u need a blue card to get in that world. pls help me. i want to see it again and show it to a fiend of mine.
