The boy is perhaps in a place he absolutely despises in the city, somewhere which he would do anything to get away from. Maybe darkness represents times of depression and swimming may represent struggle. These fears may also represent something about his life, for example he may have been controlled a lot by other people or bullied (linked into people/socializing). He had a fear of spiders, swimming, heights, darkness, being controlled and people/socializing. The boy dies somewhere in the forest and is placed in his own personal hell, where his fears are animated and emphasized to the most horrific extent possible. All the contents are fears, struggle, social barrier and post-traumatic estate of the boy's sister's death.

When they meet at last, according to the Oldboy theory, there was something unusual and bizarre, though they at last met in peace (flies were buzzing at the last scene). The game symbolizes a gruesome journey of a boy to reach his sister.

The story begins where the film Oldboy (2003) leaves off.
