Yeong Ho completely dominates Gi Tae and his gangmates. An eleventh grader comes up to Yeong Ho after hearing what happened and offers him the spot Gi Tae was in, but Yeong Ho refuses. Meanwhile, Dae Chun who was suspended for school bullying is back and he's been keeping a low profile but the eleventh graders have been poking around.
Dae Ho can purposefully control his dream environment while lucid dreaming.
His child gets kidnapped, and in order to unpack the facts he’s buried in his memory, he has to get the help of someone who can send him back into his dreams while half-awake. They race against the clock while poking around in his dreams for clues about the crime, which he collects in bits and pieces.
Jong Du is autistic who ignores society's rules; unaware or unconcerned with the consequences of his actions. Unable to hold a job and always on the edge, he has been in jail three times: for attempted rape, for causing an accident while drunk, and for armed robbery.
On the spur of the moment, he decides to visit and apologize to the family of the man killed by his brother. When he arrives, he finds a husband and wife moving out of their apartment, leaving the husband's seriously disabled sister, Gong Ju, for the neighbors to look after.
Jong Du and Gong Ju slowly begin a friendship based on their mutual feelings of isolation. He provides her with the closeness she desperately needs; and she has found someone to care for, for the first time in her life.
As their relationship becomes known, both their families are scandalized; and aided by the prejudices of society, transform the innocence of their love into something sick and twisted.
